Systems and methods for handling and dispensing of items

ABSTRACT

Embodiments of product handling systems facilitate transfer of individual product items from incoming bulk form into dedicated trays for inspection, sorting, selection, and packaging. Inspection may comprise interrogation of product items within a tray by electromagnetic (e.g., optical, hyperspectral) or other (e.g., physical, acoustic, gas sensing, etc.) techniques. Prior to packaging, product items disposed within the tray may be stored in a moveable carousel responsible for controlling environmental factors such as temperature, humidity, illumination, ambient gases, product-to-product interactions, and/or others. Movement of product items from a carousel&#39;s transfer station to an outside staging position may be accomplished using robots and/or conveyor belts. Embodiments may allow rapid, low-cost consumer selection of specific individual product items based upon their accompanying metadata (e.g., source, identifier), in combination with the results of inspection (e.g., visual appearance). Embodiments may receive product items pre-packaged in tray format to expedite inspection, sorting, selection, and packaging.

BACKGROUND

Efficient handling of many different types of items that exhibit avariety of shapes and/or sizes, can pose an increasingly complextechnological challenge. For example, produce items alone offered by aconventional grocery store, may exhibit sizes ranging from that of araisin to that of a watermelon. Moreover, the quality of such produceitems can degrade over time, affecting their monetary value.

SUMMARY

Product handling systems according to embodiments facilitate transfer ofindividual product items from incoming bulk form into dedicated traysfor subsequent inspection, sorting, selection, and packaging forconsumption. Inspection may comprise interrogation of product itemswithin a tray by electromagnetic (e.g., optical, hyperspectral) or other(e.g., physical, acoustic, gas sensing, etc.) techniques. Prior topackaging, product items disposed within the tray may be stored in amoveable carousel that is responsible for controlling environmentalfactors such as temperature, humidity, illumination, ambient gases,product-to-product interactions, and/or others. Movement of productitems from a carousel's transfer station to an outside staging positionmay be accomplished using robots and/or conveyor belts. Embodiments mayallow rapid, low-cost consumer selection of specific individual productitems based upon their accompanying metadata (e.g., source, identifier),in combination with the results of inspection (e.g., visual appearance).Some embodiments may receive product items that are already pre-packagedin tray format in order to expedite inspection, sorting, selection, andpackaging.

An embodiment of an apparatus comprises a frame translatable to astaging position in front of a carousel, and a fork supported by theframe and configured to extend in a direction toward the carousel toengage a tray holding an item. The apparatus further comprises amoveable member configured to project vertically into a first opening ofthe tray, contact the item at a first point, and to dispense the itemfrom the tray in a direction away from the carousel, into packaging.

DESCRIPTION

FIG. 1 is a simplified isometric view of a product handling systemaccording to an embodiment. FIG. 1A is simplified side view of theembodiment of FIG. 1.

In particular, product handling system 100 comprises an initial sorting,inspecting and tray loading areas 102 that are configured to receivebulk items. This input region 102 is in turn in communication with trayconveyor network 104.

In this particular embodiment, the tray conveyor network is locatedabove a second customer conveyor network 106. However, this is notrequired and the relative vertical locations of the first and secondconveyor networks could be reversed, or in accordance with still furtheralternative embodiments, the two (tray, customer) conveyor networkscould be positioned at a same vertical level. According to yet otherembodiments, the separate customer conveyor network that deliverspackages for output, can be located on an opposing side as the incomingtray conveyor network.

Trays are fed along the tray conveyor to the input area from a traybuffer 108. The tray buffer in turn receives the trays from a traywasher station 110 that functions to sanitize the trays once they havecompleted their previous product handling activities.

As further shown in FIG. 1, once product items are disposed onto thetrays, the trays move along the tray conveyor belt from the input regionto the carousels 112. There, the trays are loaded (e.g., by a robotand/or conveyor 113) into the carousels for storage under controlledconditions.

As previously mentioned, the product handling system of FIG. 1 furthercomprises a second, customer conveyor network 106 that is located at alower level relative to the upper, tray conveyor network. Thisparticular embodiment shows the customer conveyor network 106 as adouble lane configuration.

For particular embodiments utilizing conveyor belts, those conveyorbelts may cause fixed separation between transported trays and/orpackaged product items. The belts may be imaged to determine cleaningneeds. A conveyor belt may be configured to lift layer-by-layer, and mayfeature grooves and or duster-like lifters. Certain embodiments mayprovide a human-assisted station sharing a conveyor with robot lifters.

Via the customer conveyor network, the customer packaging deploymenttool 114 provides empty product packaging (e.g., a bag or box) to thecustomer packaging loading station 118 that is proximate to thecarousel. There, individual product items are loaded from the tray intothe product packaging, and transported via the customer conveyor networkto a shipping dock 120 and thence to the customer in packaged form.

FIG. 1B is a simplified plan view of the embodiment of FIG. 1. FIG. 1Bshows an incoming pallet 122 of individual product items 124 (e.g.,apples) in bulk form. Each individual product item is inspected 125 andthen disposed in a known location on a tray 126. As shown at 128, thetray will be moved by the tray conveyor network to the appropriatecarousel and be placed into storage with the product items disposedthereon.

FIG. 1C is a simplified enlarged isometric view of the embodiment ofFIG. 1 illustrating six carousels 112. The enlarged view of FIG. 1C alsoshows an aisle conveyor 119 linking successive carousels, as isdiscussed further below.

FIG. 1D is another simplified plan view of the embodiment of FIG. 1B.When an item from the tray is selected by a customer, the tray will exitthe carousel. In this particular view the tray of FIG. 1D is shownexiting a different carousel than in FIG. 1B, to which it may have beentransported during an intermediate stage via the tray conveyor network.

The unloading equipment 130 will remove from the tray, the particularitem that has been requested by the customer. The tray will return backinto the carousel until called again or empty.

Once the order is fulfilled, the customer conveyor network willtransport 131 the selected product item 124 together with the customerpackaging 133 to the shipping or distribution area.

It is noted that is some embodiments, the conveyor belts transportingthe customer package, may also move a passive or active device adjacentto some or all of the packages. That device may assist the placement ofthe items into the bag or box.

An example of a passive device could have spring loaded ‘landing pads’or an active height controlled ‘scoop’. With the latter, the items landinto the scoop (which can change height, and then drop into a package).Another example of an active device could be a robot. The devices (whichmay also have cameras) can be powered through the conveyor belt (wiredor induction) or be battery powered.

While the above description has indicated the loading of incomingproduct items onto trays, this is not required by all embodiments.According to alternative embodiments, items incoming to the producthandling system may arrive already disposed onto a tray.

An example could arise for standard items (e.g., boxes of cereal).There, each cereal box product item could be associated with data suchas an expiration date (and potentially an individual serial number).

Trays could arrive pre-loaded with non-standard items (e.g., produce,individually cut deli/cheese/meat . . . , others), and already beassociated with individual product item data such as images or othersensor data. The incoming tray may also include a mechanism formeasuring and storing environmental conditions since packing into thetray took place.

Such post-tray packing environmental conditions can include temperatureand vibrations/impact (e.g., via a G meter). Thus a system according toan embodiment would receive the pre-packed tray for handling, as well asdata associated with that particular tray.

According to certain embodiments, product handling systems may also beused to break down packages comprising one product each, into otherpackages having specific mixtures of product items. In such a ‘breakpack’ implementation, a distribution center breaks incoming packages ofone item type (e.g., typically from the factory) into mixed packagesintended for the neighborhood grocery store to replenish what has beenconsumed (e.g., 3 boxes of cereal A, 6 tuna cans, 3 salt shakers, etc.)

It is further noted that temporal factors (e.g., delivery urgency) mayimpact the manner in which individual product items are dispensed fromthe carousel into packaging. Thus where necessitated by a deliverydeadline, under a ‘split bag’ mode of operation a product handlingsystem could utilize more than one customer package to fulfill acustomer order. There, the more urgently needed item(s) would dispensedinto packaging first, followed by less urgent items being dispensed andshipped in a different package.

Product handling systems according to embodiments could alsopre-calculate and store estimates regarding time of order fulfillment.Such expected fulfillment data could be referenced by the system indeciding whether or not to resort to the split-bag mode in order to meetan urgent order.

An exemplary sequence of actions that may be performed by a producthandling system according to an embodiment, is now described inconnection with the flow diagram 1000 of FIG. 10. First, at 1002 theincoming material in bulk form is received for transfer into the traysif necessary.

The transfer of product material into the trays can be automatic orperformed manually. In the case of automatic transfer into dedicatedtrays, products are placed or dumped by a human or mechanical tool, orpicked by a robot onto a conveyor.

At 1004, the conveyor will sort the individual product items in anordered fashion for inspection. During an inspection process 1005, theindividual product items are imaged/inspected, and the images/data areassociated with each item (e.g., as metadata).

After inspection, the system will load 1006 each product onto trays andtransport the trays to the storage area (e.g., carousel). In some cases,the items are sorted in the Trays based on certain criteria (e.g.different size, quality or ripeness in different Columns)

Once transferred to a known location on the tray, at 1008 thatinformation will be maintained at least until the item has been placedin packaging for delivery. All or some of the data and metadata may bestored for longer to permit learning once feedback from a customer orother entity is obtained on the items.

At 1010, the Trays are loaded into carousels. The trays may be loadedmanually or automatically. The trays may be loaded through the same doorfrom the product items are later dispensed, or (as in the illustratedexamples) through a separate door or level. In one possible alternative,the trays remain within the carousels and the items are loadedindividually. Alternatively, the trays are loaded onto other trays nextto a carousel and placed in the carousel manually.

At 1012, when an item is selected by a customer and needs to bedispensed into packaging, the carousel may bring the tray to thedispensing door. There, the tray may be moved to the staging positionfrom which individual items will be dispensed. The tray may be moved bya conveying element within the carousel, or by an external liftingmechanism (e.g., belt or robot). Alternatively, the individual productitems could be dispensed from the tray while the tray remains within theCarousel.

From the staging position, at 1014 items are dispensed from the traysinto packages (e.g., delivery, inner, or transient) which are movingalong an aisle conveyor. Alternatively, the packages may be moved by anindependent motion vehicle/robot.

The aisle conveyor is positioned to support one or more parallel rows ofcarousels along its direction of travel. The aisle conveyor carries thevarious packages and potentially the inbound trays (e.g., with productitems) and outbound trays (empty, expired, or otherwise pulled out ofthe system).

The packages may be moving continuously or indexing and stopping nearthe staging positions. The packages may stop at every staging positionalong their aisle or as needed. The packages may step at fixed intervalsor as needed.

Packages may be placed into an aisle conveyor in coordination withplaced orders and the expected availability of items for conveying fromstaging positions along the aisle. Alternatively, transient packages areplaces at fixed intervals.

Specific packages (e.g., including specific inserts if needed) may beplaced in the aisle conveyor for specific orders. If the exact number ofpackages needed per order is not accurately known in advance (e.g. acertain order may not fit in one package) than extra ‘buffer’ packagescan be placed in the aisle conveyor every several packages.

A package may travel on more than one aisle conveyor to collect theneeded items for a particular order. Alternatively, the delivery packagemay travel on one or more aisles and either/or transient packages orinternal packages will travel down one or more other aisles.

In this case the items may be merged into one or more delivery packagesmanually or automatically. Additional items deemed too large or fragilefor automation could also be manually added to the shipment at the endof the aisle conveyor.

As described herein, robots may be used in one or more stages of theproduct handling sequence. Examples of product handling activities thatcan be performed by a robot can include but are not limited to:

-   -   manipulating individual product items for inspection/imaging;    -   loading individual product items from bulk form onto known        locations on trays;    -   moving trays into/out of carousels;    -   dispensing individual product items from known tray locations        into packaging.

There can be one or more robots per location in the product handlingsystem. Robots could be optimized in terms of weight and grip to thespecific product items and/or system components (e.g., trays). One robotcan have several grippers, switch grippers, or each of the robots canhave a different gripper.

The robots may reference various pieces of information to grab a productitem. Examples of such information may pertain to tray layout, imagestaken on the main or side-conveyor before, and/or dedicated images takenproximate to the robot (or on the robot's arm).

Robots can be of various types, including but not limited to cartesian,Selective Compliance Assembly Robot Arm (SCARA), cylindrical, delta,polar or a 4- or 6-axis articulated robot. Robot grippers can usepressure by rigid or flexible fingers, vacuum/suction, magnetic,electrostatic lifting, leaky vacuum (e.g., Bernoulli lifters), or acombination thereof.

A robot may use features within the trays in order to allow the liftingof product items, especially delicate/damageable items. In certainembodiments these can be rake/dustbin like, grabbing items which havebeen pin-lifted (e.g., from below with a potential balancing/locking‘thumb from above).

Packaging can pause adjacent to carousels or can have a parking area forone or more (e.g., three) customer packages. Multiple packages outsideof a carousel may all be reached by the robot, or they may need to moveto a specific parking position for the robot to reach.

Owing to its intimate relationship with the product being handled, thetray component forms one component of a product handling system.According to certain embodiments a tray may be wider than it is tall.

In some embodiments, a tray may comprise a formed sheet of plastic ormetal, that holds individual items or containers of items, in acontrolled order while the tray moves through the system.

Product items may be disposed on the tray loose (e.g., an individualapple). Alternatively, product items may be contained within a box(e.g., a box of tomatoes).

A tray may receive one type of item as a standard, but may also receivemore than one variety. This may occur for a low consumption items. Atray may receive a subcategory of an item (e.g., oranges between 3 and 4Ounce Vs oranges 4 and above.)

Some product items may be partially packaged. Examples include parsleytied with a rubber band, bunches of bananas, etc.

Product items may be individually labeled, for example with bar codesand/or RFID tags. The tray itself could have a bar code, RFID tag, orsome other marking to permit tracking if needed.

Product items within the trays may be arranged in rows and columns. Rowsmay be oriented parallel to the edge of the tray from which they areunloaded. Columns may be separated by barriers to allow product items toarrange within the columns utilizing grooves or other shaped features.

Specific embodiments may sort the items such that each bin is within adifferent Column. Here, bin may represent the quality, size, appearance,or a different product type.

Trays may be open, or have an opening wall at one or two of the edgesparallel to the rows. Alternatively, trays may be closed on all sides.

Trays may have openings, grooves, holes, or other features to allowlifting and/or movement of the product items from below. FIG. 2 shows aperspective view of a tray according to an embodiment. FIGS. 2A-2B showedge and plan views, respectively, of a tray embodiment. The tray 200includes grooves 202 and slots 204.

Certain tray features may hold a particular type of product or a certainvariety (e.g., stone-fruit of a given size range, oval shape,loose-leaf, etc.) FIG. 3 is a plan view of an embodiment of a trayhaving groove features configured to hold stone-fruit 300 items.

Trays exhibiting different features may be employed to effectivelyhandle various product types. Trays may maintain product items at aknown location that will not change during transportation.

Trays may be designed with sufficient spacing and other features topermit tasks such as imaging, scanning, sensing, and/or lifting. Traysmay exhibit features to allow removing the tray for packaging, orremoving the tray from the product handing system.

Embodiments of product handling systems may inspect the trays forcleanliness and integrity. Trays can be single or multi-use.

Some tray embodiments may feature a multi-use part covered by asingle-use layer. Such a single-use layer may comprise paper, plastic,cardboard, or other materials.

Embodiments of product handling system may include mechanisms forcleaning the trays after some or all the product items have beenremoved. Cleaning can include washing, brushing, electrostaticdischarge, UV, steaming, or other disinfecting techniques.

For purposes of imaging, product items that are to be transferred totrays, may be loaded into transfer conveyor belts. Such conveyor beltsmay have imaging and/or other sensing stations.

Examples of imaging techniques that may be employed can include but arenot limited to:

-   -   multispectral imaging    -   hyperspectral imaging    -   acoustic or acousto-optic sensing    -   optical spectrometers    -   3-dimensional imaging    -   UV imaging    -   visible imaging    -   infra-red (IR) imaging    -   mass spectrometry    -   x-ray imaging.

Examples of sensing technology that involve other than electro-magneticimaging can include but are not limited to:

-   -   chemical sensing (e.g., smell sensing technology); and    -   physical sensing (e.g., spring loaded firmness gauges or        weighing—of either individual items or trays).

All items, or a sampling thereof may be imaged and/or sensed. Theproduct items can be imaged or sensed individually, or collectively orin sub-groups.

Weight can be estimated from produce size and/or from produce sizerelative to other produce in the tray when the total weight of the itemsin the tray is known.

Weight can be determined if the item is lifted by a robot. That weightcan be used to improve the estimation.

The imaging and/or sensing may occur while the product items are locatedon a transfer conveyor belt, are grabbed by a robotic arm, or as theproduct items are rolling or dropping before being disposed on a tray.

A transfer conveyor may be optically transparent to permit imaging ofproduct items from multiple sides and/or accessible angles. However,items can also be grabbed and lifted for inspection, imaging, orsensing, or simply raised such as via cushioned pins projecting thoughholes in the conveyor belt and/or tray.

Additionally, secondary imaging/inspection can occur during storage, orprior to dispensing a product into a package. Such imaging/inspectioncan be used as a final go-no go verification step after the attributesof the product item have been determined from previous imaging.

Other sensors and/or imagers may be used to confirm the successfultransfer of trays, items, and packages.

As described below in detail below, the product handing system maycomprise the trays utilized in conjunction with carousel elements. Oneor more sensors or cameras may be installed within the carousel.

Such carousel sensors/cameras could image some or all of the items asthe carousel rotates (e.g., a part of regular motion or to specificallyallow imaging). Several images could be taken during the motion topermit viewing from different perspectives, and even optionally 3-Dreconstruction of the product.

Some embodiments could install cameras at the top of the carousel toafford a view of the top tray. The cameras can be positioned on top inthe front and in the rear in order to ‘triangulate’ an image.

Items can be imaged once upon entering, periodically (such as every day,using the off-hours for example) or based upon other rules. Items can beimaged from the top while supported in the trays, and then flipped overindividually or as a whole tray to be imaged from the other side, orotherwise manipulated to rotate so they can be imaged from the otherside.

The imaging can take place on the main conveyor belt, and/or on the sideconveyors, and/or at the storage cabinets, and/or at the parking spotsbefore a robot manipulates the item.

A block may represent a plurality of trays. A given block may contain aset of items (e.g., all fruit and vegetables, all dairy, etc.) and isexpected to hold many (e.g., tens, hundreds, or even thousands) ofunique items.

A block may contain all or some of the items for sale. The block mayhold several trays of frequently accessed product items in order toensure rapid supply. Conversely, a block may have partial trays or evennone of rarely-accessed items that will instead be loaded upon demand.

The conveyor belt may lead to a set of modules that may be situatedorthogonally on one or both sides of the conveyor belt. The modules maybe dedicated for a specific variety of items (like fruit versusvegetables, packaged product items versus loose product items, etc.).Specific trays can be moved to side conveyors of individual modules asthey pass by on the conveyor.

According to embodiments, a loading mechanism may be employed to moveproduct items to and/or from the trays. In particular, once productitems have been inspected (e.g., by imaging and/or sensing), they aresorted onto trays.

One method to accomplish this sorting is to move the items alongconveyor belts. The trays (e.g., with slots) can be positioned above alifting conveyor. The lifting conveyor will lift through the tray andthereby allow the product items to be conveyed over the tray.

Once in place, the conveyors will move down and the items will rest onthe tray. This is depicted graphically in the plan view of FIG. 4, wherethe product item 400 is disposed on the tray by the conveyor 402. Thetray can then move on to storage (e.g., in a carousel).

Various stations could be used to match the variety of the items.Alternatively, an automatically adjustable conveyor could accommodateall or many of the possible varieties of product items.

In certain embodiments, trays having product items already disposedtherein, will be loaded into carousel elements. According to analternative approach, product items may be loaded into the trays thatare already in the carousel.

FIGS. 5A-D show different views of one example of a carousel 500according to an embodiment.

The carousels may be oriented in a horizontal direction, containingseveral tens of trays. The carousels may exhibit the ability to bringindividual trays to the transfer station 502, from which they can bemoved onto the staging position 504 (FIG. 5C).

The carousels may operate in a continuously indexing manner, bringingfollowing trays to an offload station. Alternatively, the carousel maycall trays in turn as needed.

Each carousel may operate with its own specific controlled environmentalconditions. Examples of such conditions can include but are not limitedto:

-   -   temperature,    -   humidity,    -   specific gases (e.g., ozone)    -   illumination    -   product-to-product proximity and interactions    -   mold growth.

According to embodiments, a carousel may have an opening (e.g., slit)for loading and unloading. The opening could be parentally open, anactively actuated gate, opened/closed by the motion of the tray, orclosed with a material permitting tray motion (e.g., a plastic sheet).

Carousels may be designed to allow placement of trays with differentspacings. This can permit handling of product items exhibiting differentsizes (e.g., heights).

Alternatively, trays may be designed with fixed spacing. A controlprogram may dictate which slot is appropriate for each tray height. Asingle carousel (one motor) could turn one or more columns of Trays.

Carousels may be designed with belt in cameras and sensors to continueto monitor the products as they age. One specific design could have thecameras or other sensors located at the top of the carousel path,inspecting the products in the tray passes past the top.

Additionally, there could be reject mechanisms built into the carouselsto allow items to be automatically removed from the system. One designcould employ lifting conveyors at the bottom of the carousel path. Theseconveyors are able to lift up and remove an item from the tray asneeded.

Trays can be removed from the carousel manually or automatically. Inautomatic embodiments, the tray can be transported out by a walkingbeam, a walking beam conveyor, or a conveyor or rollers built into thecarousel itself.

For walking beam embodiments, the carousel could stop with theappropriate tray in front of the dispense door. One or more beams wouldmove into the carousel, lift the tray up and pull it out of the door anddown onto a conveyor belt or rollers.

For the case where the conveyor is built into the carousel, each row ofthe carousel could have its own set of belts or rollers actuated toremove the tray. Each row could have its own motor, or a single motormay engage with the conveyors at the dispensing door.

Once located at a staging position, the tray will be in proximity to theaisle conveyor. This will allow items to be transferred from the tray atthe staging position to the packages.

Referring now to FIG. 6, conveyor belts 602 can rise up through openings604 in the tray 606. Product items 608 may be moved along a conveyorinto a position 610 from which they will be transferred 611 to thepackage, or into a separate transfer mechanism that will move theproduct items to the package.

FIG. 6 shows a perspective view of a tray with product items disposedtherein, interacting with a transfer mechanism 600. FIGS. 6A-B show planand edge views, respectively.

The product items may also be pushed, lifted, or dragged from the trayto that position for packaging. Product items could also be individuallypicked by a robot and an End of Arm Attachment (EOAT) specially designedfor secure engagement.

Once the product item or items have been removed from the tray, the traywill be conveyed back into the Carousel to store the remaining items.

Details regarding a transfer mechanism for moving the product itemsapart from the tray according to embodiments, are now discussed.Specifically, once an item is out of a tray, it can be moved to thepackaging by multiple methods.

One method is to have a robot pick up the item and place it into thepackaging. Here, there may be specific EOATs for various classes andsizes of products. Some EOATs may have suction cups, others may havegrippers, still others may shovel items up.

An alternative method is to have the product items fall off of the endof a conveyor into a receptacle such as a rigid box or flexible bag,which may or may not have padding to break the fall. FIG. 9 shows anexample of such an embodiment featuring receptacle 900.

The item could fall onto a spring-loaded slide or flap that drops downinto the bag or box to soften the landing. The bag or box could beactuated to lift the box up to the edge of the conveyor. The box couldalso be constructed in a manner that the one more sides of the bag orbox temporarily collapse to allow items to be brought into them.

A third possible approach is to employ a vertical conveyor whose belthas large flaps to hold the product item. FIG. 8 shows a side view ofsuch an embodiment which includes flaps 800.

The conveyor would lower into the bag or box, or the bag or box couldrise up around the conveyor. The conveyor could be actuated in a mannerto select the location to drop the item in the box or bag.

A fourth approach is to have the item move above the package on aconveyor. Once in position, the conveyor pivots down like a trap door.FIGS. 7A-C are side views showing the operation of one such embodiment.

The conveyors could lower down into the bag, controlling the decent ofthe item until it is beyond the reach of the conveyor. The belts couldbe made of a thick foam that helps capture the items on the way down.There could be two or more belts on each side with various spacing thatcan process various sized items. Each station could be designed for acertain shape, weight or volume. Or, one design could be actuated in away that the location of each belt is movable to handle item variety.

A fifth method is to push or pull the product items from the back of thecolumn or row of the tray. This could be accomplished from above via amechanical gantry system, from below via an actuator through a slot, orutilizing a robotic arm.

A sixth possible method is to convey the product items through a holewith a stack of mesh or plastic rolled onto it. As the items are pushedthrough, the bag will roll forward until full and then be terminated andclosed.

Certain embodiments could feature one transfer mechanism per tray. Otherembodiments could feature one transfer mechanism per column or row ofthe tray.

There could be one or more transfer mechanisms per carousel. Thetransfer mechanism may be actuated in such a manner as to move betweenpositions. Alternatively, the individual product items could be liftedonto conveyors at the staging position and then conveyed to one or morefixed transfer mechanisms.

Embodiments of product handling systems may permit customer selection ofspecific items. In some cases, e.g., produce or other non-uniformproducts (meat, deli cheese, etc.,) the consumer may be offered theability to choose from a number of specific items.

According to such embodiments, images or other (e.g., sensing) dataprovided to customer, may allow him or her to successfully execute theproduct selection. The specific item may be reserved for a certainamount of time allowing the selection. Once selected by the customer,the specific item will be vended from the carousel.

Certain embodiments may allow dispensing only from the front row (e.g.,closest to the package). There, customer selection may be limited to thefront row, and/or selection of sequential items in the same column willbe possible.

In alternative embodiments, a series of conveyors could move some itemsout of a column or row, so that an interior item can be vended to thecustomer. Then, the conveyors could move the remaining items back intothe tray for return to storage.

Embodiments could offer the customer multiple qualities for evaluatingwhen selecting their item. The customer could evaluate color pictures ofthe item from multiple angles. The customer could also be offeredhyperspectral images.

A system according to embodiments could show a customer a rating thatsignifies the firmness of the item. The rating could be on a scaleshowing maximum firmness for similar items. For example, the firmestpear (right off a tree) could be rated with a value of 10, while a pearon the day of expiration could be rated a value of 0.

The scale could be adjusted based on the season of the item. Forexample, off-season produce might have a narrower range of possibleratings.

Similarly, a rating scale could be shown for various characteristics ofproduct items. Examples can include but are not limited to:

-   -   sugar content in fruit    -   the ripeness of certain items like bananas or avocados    -   an overall rating that shows our compiled assessment of the        overall quality of the item. The rating scale could be any set        of numbers or an A, B, C, D, F scale or similar.

Product handling systems according to embodiments may include mergingand/or shipping areas. At the end of the aisle conveyors, other conveyorsystems (or product moving mechanisms) may transfer packages either toother aisles or to a shipping area.

Multiple packages can be merged into one or more delivery packages. Forembodiments featuring transient packages, individual items may be liftedor otherwise transferred (such as poured) into delivery packages.

Product handling systems may feature a buffer station where packages arewaiting. This waiting may be for other Packages in the same shipment, orfor other reasons.

The nature of delivery packages according to embodiments, are nowdescribed. Delivery packages can be bags, simple boxes, or boxes havingspacers inside.

One packaging option is for single layer stackable boxes. Another optionis to have boxes with several heights, with the box ultimately useddetermined by the largest item it is designated to hold.

A box height could be a designed to have 1 or more layer, with apackaging material for contact with fragile items, and remaining layersfor regular items. Packaging for a fragile layer could have a formedplastic or cardboard insert sized to fit various types of items (e.g.,round, oblong, flat, etc.)

Packaging may be single use from recyclable material, and may berecycled. Packaging could also be designed to be returnable from thecustomer.

Transient packages can be individual bags or boxes with items collectedinto a larger box. Transient packages can be a large tray on which itemsin an order are placed for transport to the packing area.

Several delivery packages can be collected for one customer order. Thiscan, for example, be by employing vertical stacking or nylon wrapping orother technique.

Embodiments may employ techniques for controlling the queuing and/ortiming of product movement through the product handling system.Particular embodiments may use information from orders received, as wellas from orders that are expected. The latter may be accomplished throughmachine learning techniques that are keyed off of past behavior.

One example of product movement that may be coordinated, is to sendpackages into aisle conveyors. This package sending may be for delivery,internal movement only, or for transient packages.

Another example of product movement that may be coordinated according toembodiments, is to bring trays to an unload position from the carouselsand to the staging position. This movement may need to be done in timeto preempt the loading of specific items into the packages.

Still another example of product movement that may be coordinated isaction to bring trays, transient packages, or customer pack boxes to therobot loading area. The activity of the conveyors, carousels, andloading mechanisms may be coordinated in order to maximize systemthroughput and minimize time from receipt of the order to packaging.

Embodiments of product handing systems may function to optimize locationof items on trays, and the location of trays in carousels. This allowseach carousel and packaging location to be fully utilized.

Embodiments may track performance of the various components. An overallsystem health may be displayed to the users.

Embodiments of product handling systems may also operate to plan theoptimal packing, for example calling upon specific pack boxes as neededto fulfill each order. In one embodiment, the system may place larger,heavier items at the beginning of a cue so that those items are at thebottom of the packaging. Then, as the packaging gets filled,progressively lighter and more fragile items can be positioned on thetop.

Embodiments could also function to determine where in the box aparticular item should be placed. This allows knowing where productitems are located through the entire packaging sequence.

The imaging and sensing data collected from the product items (as wellas other available information such as images or othermeasurements/information taken before arrival at the facility) may beused to attribute properties to the item. Such other information caninclude data provided on barcodes or similar mechanisms such as RFIDtags. These can be located on the individual item, on the incoming tray,or be traced to the incoming shipment. In some embodiments the otherinformation may be measured ‘off-line’, such as a sample of fruits thatare sent to lab tests or tasted.

The customer can be offered various packages if desired. In one example,produce could be selected based upon an expected day of ripeness. Thusan instruction received from the customer may be to “select 7 bananas,one that ripens every day for the next week”. Alternatively, a customercould request a box of fruit per day, each box ripening as needed.

In another example, a customer could select kits specifically intendedfor a certain recipe. Thus bananas slated for use in banana bread, couldbe ordered as bananas slightly paste their ripe stage.

Further alternatively, a customer could order a lasagna kit. During theselection process, the customer could be offered a list and choose someor all of the ingredients from that list.

Embodiments may allow external links to be placed on recipe sites, sothat a user can add the recipe to their list of saved recipes. Forexample a customer may prefer the pasta sauce available from aparticular website, and click the save recipe option. Then, that productitem will be added to the customer's profile.

Later, the customer might look through their recipes and plan out mealsfor the week by selecting each meal and the day it is expected to beeaten. Embodiments could then sort through the order and select items ofthe best quality on the day scheduled for consumption.

According to embodiments, the product handling system could also belinked to other Internet-of-Things (IoT) devices that are able todetermine or predict particular items already present in a customer'srefrigerator or cupboard. Those particular items may then be able to beautomatically ordered on a recurring time period. Alternatively, when arecipe is ordered, items already possessed by the customer can beautomatically removed from the list.

A system according to embodiments could be linked to voice controlleddevices. This allows a user to add an item to their grocery list so thatit can be saved for a future order. A customer could accomplish this byasking to have items saved to their cart, or by notifying the system ofa deficit of certain item. Information relating to particular dishes orrecipes could be saved in a similar manner.

System users may have the ability to save past quality preferences. Thusif a customer ordered B level zucchini (for example), that customercould mark a box saving that preference for all future zucchinipurchases. This shortens check out time and improves consumerconfidence.

Imaging and other (e.g., sensing) parameters may be stored forsufficient time to allow comparison after customer feedback has beenreceived. (This may be about a week for fresh produce purchases.) Thestored information could be the raw data or a subset thereof that hasbeen processed (e.g., for compression or encryption).

Parameters or ratings can be referenced to offer different pricingschemes or dynamic (adjustable) pricing based upon quality and/orsupply-demand variations.

A customer can provide feedback on particular parameters of thedelivered product. Examples of such parameters can include but are notlimited to the quality, ripeness date, blemishes, or other parameters ofpurchased produce.

Systems according to embodiments may utilize machine learning to processfeedback information together with other collected parameters (e.g.,images of product items). This allows the system to improve an accuracyof predicting general properties (e.g., ripeness day, color, farm, andother attributes) as well as the preferences of a specific customer.Such data processing can aid customers in obtaining preferences, allowsellers to evaluate supplier performance, and permit suppliers tocollect valuable quality control information and improvement feedback.

The user interface (UI) may include virtual or augmented reality imagesor scenarios. In one example, a user could enter a virtual supermarketwhere they can inspect and select the specific to be placed into theircart. Such a virtual store environment can be optimized to minimize timespent by down selecting items in an order they are shown according topreferences.

Product items not normally bought by a particular customer can bepresented for inspection (including physical handing).

Recipes offered by the system accompanying product items, could beavailable for customer review to inform about possible uses for theproduct. If a recipe is selected, the user can be solicited to add theother recipe items to their cart. Alternatively or in addition, a userselecting a recipe could enter a virtual environment displaying finisheddishes or recipes for ordering other ingredients as desired.

According to embodiments, a product handling system can provideestimated packing time based upon factors including but not limited to:

-   -   the order contents    -   other orders in the queue, and    -   the known content of the block containing other orders.

A product handling system according to embodiments could suggest changesin the order to reduce pack readiness time. The system could alsoactively suggest changes to the order based upon price considerations,for example to meet a budget requirement.

EXAMPLE

An example of a product handling system is now described. An embodimentof an automated system allows rapidly distributing a large number (onthe order of many 10,000's) of unique incoming products into packagesfor customer delivery.

According to one embodiment, the system provides an automated grocerystore offering rapid (e.g., minutes) fulfillment and packaging. Inparticular, grocery items typically involve 1,000s or 10,000s of uniqueitems.

For example, individual product items in the field of fresh produce, maycomprise a large volume of associated data. That is, an individual fruitor vegetable (e.g., an apple) may be associated with one or more of thefollowing pieces of information:

-   -   product item identifier (ID)    -   size    -   color    -   variety    -   harvest date    -   source (e.g., farm)    -   visual inspection result    -   non-visual inspection result (e.g., softness, gas sample, many        others)

This information could be stored in electronic format in anon-transitory computer readable storage medium. In one example, theinformation could be stored as fields in a data object stored in adatabase. The information could travel associated the particular productitem, together with product handling specific data (such as a trayidentifier, tray location identifier).

Upon user selection of the particular product item (e.g., apple), theproduct handling system could dispense the item to the consumer togetherwith packaging (e.g., box, bag, together with any insert) within a shorttime frame.

While this particular example describes an embodiment that is designedfor use in the packaging and delivery of fresh produce, this is notrequired. Other potential applications may call for the rapidfulfillment from a large number of product options, for example in thearea of recycling of clothing or other items.

Particular embodiments may be especially suited to allow rapiddistribution of a large number (on the order of many 10,000's) of uniqueincoming products into packages for customer delivery. By contrast, aconventional on-line retailer may carry millions of different individualitems in warehouses for delivery.

Embodiments may thus offer a space efficient solution that may be localwithin proximity of customer demand. However, some embodiments could belocated in larger warehouses outside of densely populated areas. Systemsmay permit a high level of quality control, allowing customers to avoidthe inefficient travel to and from a store in order to select individualitems for freshness and relevance.

In summary, embodiments may offer optical (hyperspectral, potentially3D, potentially multi-angle) or other (like acoustic, pressure gauge,gas sensing systems, spectroscopy) inspection of some or all incomingmaterial (e.g., loose produce) in bulk form.

Embodiments permit customer selection of specific product items (e.g., aparticular tomato) based upon one or more of the following:

-   -   specific information (images)    -   specific or aggregated sensor data    -   typical images (of others that we sorted into same bin)    -   meta data accompanying the items (manufacturer's location and        pick date if applicable, storage and transportation conditions,        etc.)    -   the rank of a specific item within a larger aggregate of items    -   other criteria (such as size, weight, volume, color).

Embodiments may offer storage of product items within carousels thatcontrol multiple environmental factors (e.g., temperature, humidity,product to product proximity and interactions, mold growth, gasdetection). Such a carousel-based storage system could be designed toallow rapid packing of individual products to provide rapid orderfulfillment.

Embodiments may allow the vending of fresh produce into either adelivery package, an inner package, or a transient package. Here, aninner package represents a tray that will later go into a box withothers. A transient package serves just to carry the product item(s) toa place where a shipment package is consolidated.

In the case of direct vending into a delivery package, that packagingmay include a generic form of spacing or cushioning or an insert thatwill be placed before loading based on the expected items to be placesinto that delivery package (e.g., round indents for the packaging ofstone fruit).

According to certain optional embodiments, inner packages, and/orindividual items, and/or transient packages may be merged into adelivery package if appropriate.

In some cases, other material may be added to prevent damage to items inshipping or packaging. Examples can include but are not limited tocardboard, shredded paper, inflatable plastic bags, or other fillers.Alternatively, the individual dispensed product items may be coveredwith another flat or shaped surface or a stretchable or inflatablemembrane for protection during shipping.

Embodiments may permit individual item selection by a consumer based onimaging and other sensor data. This selection may be enhanced bylearning consumer preference(s) based upon image, collected data, andother sensors. This may be achieved independently, or in connection withautomated features.

Various product handling systems according to embodiments may exhibitone or more of the following features. Certain embodiments may hold fora customer, a specific selected unique product items while they are intheir cart. Some embodiments may save quality preferences of a customerfor future orders.

Particular embodiments may feature recipe buttons that allow user tosave a recipe, and select one or more particular product items of thatrecipe as part of an order. Product bundling features may facilitate auser ordering whole recipes, kits or a series of items. Variousembodiments may allow optional browsing and selection by meal optionsinstead of individual items.

Voice controlled additions to a cart may be allowed for future orders.Various embodiments may implement dynamic pricing based upon factorsthat can include but are not limited to expiration dates, consumerfeedback, and conveyor load. Some embodiments may dispense product itemsfor packaging according to expected expiration date.

FIG. 11 is a simplified diagram illustrating an embodiment of a producthandling system 1100 according to an example. Specifically, a user 1102interacts with a processor 1104 via a graphical user interface (GUI)1106.

The processor is in communication 1107 with both a database 1108 in anon-transitory computer readable storage medium 1110, and the variousother system components 1112. Specifically, those other components serveto sort 1114 incoming items, with the processor assigning each a productitem identifier that is stored in the database.

The individual product items are then inspected 1116. The processorassigns an identifier 1118 to each of the inspections, the results ofwhich are stored in the database together with the product identifier1120 and the inspection result identifier 1122.

As described extensively above, the individual unique product items arethen loaded 1124 into tray(s). Again, the processor stores in thedatabase, the corresponding tray identifier 1126 and tray locationidentifier 1128 associated with each individual product item identifier.

Next, the trays are moved to the carousel for storage 1130. A carouselidentifier 1132, and a location 1134 of the tray within the carousel,may be stored by the processor in the database associated with the otherIDs, thereby allowing tracking of tray and product item.

The specific data relevant to various product items is then communicated1136 from the processor to the GUI, where it is displayed 1138 to theuser. Based upon this displayed product item data, the user provides aninput to select 1140 a particular product item.

The processor receives this selection, and in response communicates aninstruction 1142 to the carousel. Based on that instruction, thecarousel dispenses 1144 the unique product item into packaging. Finally,the product item together with the packaging are delivered 1146 to thecustomer.

FIG. 12 shows a perspective view of a product handling system accordingto an embodiment. Product handling system 1200 includes multiple banks1202 comprising six carousels 1204 each, that are oriented in two rowsback-to-back.

Storage of particular items within a specific carousel, is typicallydetermined at least in part by the conditions of that carousel. Certainitems may be stored in groups calling for the same or similarconditions.

For example a set of fruit product items that call for a suite ofconditions such as:

-   -   high relative humidity (RH),    -   low temperature,    -   low oxygen, and    -   high CO₂,        can all be stored together in the same carousel.

Product types calling for different storage conditions, may all bestored together in a different carousel. For example, in contrast withfruit product items, certain dairy product items may call for:

-   -   low temperature, and    -   normal RH conditions.

Each carousel may thus be characterized in part by its particular suiteof environmental conditions, as well as by its physical location withinthe system.

FIG. 13 shows a side view of one carousel bank of the system of FIG. 12,with the side wall of one carousel cut away. This system utilizes atwo-level transport path configuration, with trays 1206 arriving forloading on an upper level 1208, and trays being retrieved and productsbeing dispensed into bags 1210 on a lower level 1212. Details regardingthe product retrieval and unloading process for this particularembodiment, are further described below.

Returning to FIG. 12, it is noted that multiple carousels of the sametype (e.g., “Berries”) may be present in a single system. Thisredundancy may be introduced in order to distribute the items throughoutthe system and increase bag path efficiency. Unwanted bottlenecks in theflow of materials through the system can be avoided, e.g., whereproduct(s) of a particular carousel are popular and hence need to bedispensed/replenished, often.

It is further noted that the arrangement of carousels, and even banks ofsame, may be carefully determined in order to enhance the efficiency offlow of materials through the system. For example, carousels storingitems typically purchased together, may be grouped to be physically nearone another, thereby reducing inefficiencies of travel time/distance.

The specific location of product items in the carousels can be adjustedover time. This may be done in response to the identification of productpurchasing behaviors that emerge for particular customers or subsetsthereof. Such trends may be determined with the aid of intelligentlearning approaches that are trained on past customer behavior.

Other considerations may influence carousel location within the system.For example, as described herein the placement of items within a bag maybe carefully determined, with fragile products being dispensed last, ontop of more durable items. Thus, carousels storing such fragile productsmay be located downstream in the process flow, with items ordered in away that those slated for the bottom of the bag drop first, and thoseslated for the top of the bag drop last.

In addition to relative fragility, a dispensing order may also dependupon relative product item size. Certain approaches may seek to dispensea large item (e.g., a tall box of cereal) early in the sequence, andthen dispense smaller products around it.

Returning to FIG. 13, the cut-away view shows the storage of multipletrays of products within the rotating carousel. Depending upon factorssuch as the number and quantity of products to be stored, carousels maybe of varying sizes. Examples of standardized carousel heights caninclude but are not limited to (in feet): 13.5, 17.25, 21, 24.75, and28.5. Other heights may also be used.

Conditions within each carousel are carefully maintained, and theenvironment of each selectively modified in order to extend productlife. Environmental conditions that may be relevant for storing productsin a desired state, can include but are not limited to:

-   -   time of storage;    -   temperature;    -   relative humidity;    -   gas levels (e.g., O₂, CO₂);    -   ethylene removal;    -   light exposure;    -   cross contamination;    -   Volatile Organic Compound (VOC) levels;    -   mold spore levels; and    -   cross contamination.

Detection of such conditions can take place within the carousel itself,checking multiple trays at a same time. Alternatively, such conditionscan be detected on an item-by-item basis during product intake andsorting, or prior to dispensing.

Hence, products that are desired to be maintained under similarconditions, may be stored within the same carousel. Incorporated byreference herein for all purposes, is the following document:Agricultural Handbook No. 66, “The Commercial Storage of Fruits,Vegetables, and Florist and Nursery Stocks”, printed by the U.S.Department of Agriculture as revised February 2016. This publicationprovides a table listing compatible fresh fruits and vegetables during7-day storage.

Considerations other than environment may dictate the storage ofproducts within or outside of, the same carousel. For example, consumersafety reasons may require the segregation of product items that are thesource of food allergies. Hence, the certain carousels may be dedicatedto the storing of nuts only.

Details regarding the dispensing items from the tray with a conveyorfrom below, are now provided. In particular, the product retrieval anddispensing apparatus according to particular embodiments, may offerthree services:

-   -   removing tray from carousel;    -   removing items from tray; and    -   placing items from tray into a bag.

FIG. 14 shows a perspective view of a bag 1210 (shown with handlesfolded down), that is approaching and halting in front of the carousel1209 on the transport path. The carousel 1209 may comprise a pluralityof support features 1211 configured to hold a plurality of trays. Atthis time a frame 1220 rises up to the level of an opening 1222 of thecarousel 1209.

FIG. 15 shows a perspective view of forks from the frame 1220 extending1224 into the carousel 1209 and lifting a tray 1226 present therein withone or more products 1228 disposed thereon. FIG. 16 shows a perspectiveview of the frame 1220, showing the forks 1230 extended therefrom. FIG.17 shows an end view of the frame 1220, showing the fork 1230 extendingunderneath the edge of the tray 1226 having one or more products 1228disposed thereon.

Details regarding the architecture of the machinery along the retrieveaxis, are now described in connection with FIGS. 18-19D. In particular,FIG. 18 shows a perspective view of the frame prior to the extension ofthe forks.

FIGS. 19A-D show enlarged views of the front of the frame during theretrieval process. In FIG. 19A, a drive flipper 1232 is spring loaded inthe up position. FIGS. 19B-D show that when the fork end effector isextended by the rearward drive gear 1234, a roller interface 1236 thatrides on the drive flipper pushes it down into position.

After some amount of travel, the forward drive gear 1238 engages therack. The gearing is designed so that both drive gears can interact withthe rack at the same time and pass off the rack to each other. At fullextension only, the forward drive gear is engaged.

Between FIGS. 19C and 19D, the flipper raises the forks to cause thetray to come off of its supports in the carousel. A benefit is that theback side of the forks do not stick out into space, and can be flushwith the end of the tool.

FIG. 20 is an end view of the frame with the extended forks engaging thetray as part of the retrieval process. As the forks lift the tray fromthe carousel, product conveyors 1240 move laterally 1242 to the specificpick location (i.e., underneath the row of the tray from which items areto be dispensed).

FIG. 21 shows a perspective view of a product conveyor 1240 whichincludes a slide 1244. FIG. 22 shows a perspective view of a tray 1226(here empty for illustration) lowering over the product conveyors 1240.The tray 1226 may comprise one or more grooves 1227 configured tosupport one or more items. The one or more grooves 1227 may comprise oneor more openings 1229 that are sized and shaped to allow at least aportion of the product conveyors 1240 to move through the one or moreopenings 1229. FIG. 23 shows a perspective view of the product conveyors1240 moving through the one or more openings 1229 shown in FIG. 22 tolift the products 1228 from the lowered tray 1226.

FIGS. 24A-B show side views of the product conveyor in non-extended andextended positions, respectively, including belt 1246 and fixed pulleys1248. FIG. 25 shows a side view of the extended product conveyor 1240bearing products 1228 lifted from the tray 1226. In particular, theproduct conveyor 1240 can slide forward off the tray 1226 and over thecustomer bag 1210, in order to drop the items 1228 in a specificlocation.

Here, the belt stays tensioned as it moves between fixed pulleys.Pulleys 1251 move forward and back. They stay between the outsidepulleys. This helps to ensure that tension is maintained in the belt.

Belt movement and sliding action may be driven by two splines 1250 andgears so that motors are fixed under the unit, making it easilyremovable and cleanable. As the conveyor, 1240 slides left and right tofit into the correct slot in the tray, the spline will stay engaged withthe gears that drive the sliding action and the belt movement.

FIG. 26 shows a front view of the item 1228 being moved off of theextended product conveyor 1240 into the bag.

FIGS. 27A-C are side views showing a sequence of disposing a productinto a bag according to an embodiment. At FIG. 27A, the customer bag2700 starts bunched up at the top. FIGS. 27B-C show that as the bagbecomes filled, a motor lowers the platform 2702 that the bag is sittingon, and additional items 2704 are placed on top.

A benefit of this approach is that the drop height is always the sameheight. Additionally, some items can be positioned in specific locationsby controlling one or more parameters such as:

-   -   bag height;    -   conveyor position; and/or    -   bag location.

In an example, a product in the form of a bottle of wine could beinitially disposed in the tray, oriented parallel to the productconveyors. As the bottle tips over the edge of the product conveyor, thebottom of the bottle will reach the bag and stop at an angle, restingagainst the product conveyor. The product conveyor can then push the topof the bottle forward until it is sitting upright.

As described herein, one benefit of product handling systems accordingto embodiments, is that they may allow for the full diversity ofproducts of a conventional grocery store, to be simply organized,stored, and then accessed. One feature that is particularly helpful inthis regard is the tray element.

Particular embodiments may feature two different tray types, each typeconfigured in various sizes to receive different products. A first traytype is designed to store products that are round or cylindrical inshape, and hence exhibit a roughly circular cross-section

FIGS. 28 and 28A-B show overhead and cross-sectional views,respectively, of such a first tray type 2800 according to an embodiment.Here the tray is supporting products 2802 of cylindrical shape having aroughly circular cross-section. These trays can also hold sphericalitems.

By contrast, FIGS. 29 and 29A-B show overhead and cross-sectional views,respectively, of a second tray type 2900 according to one embodiment.Here the tray is supporting products 2902 of cuboid shape having aroughly rectangular cross-section. This tray type may differ from theother tray type in not having concave features configured to receiveproduct items having a rounded cross-section.

Given these two basic types, various sizes of row dimensions may allowfor the support of a wide variety of potential products, as is describedin the following tables.

TABLE Group I (circular product cross-section) Range of Product Cross-Tray # Sectional Diameter (mm) Example Product I.1 ~30 to ~47 LooseCarrot I.2 ~47 to ~65 Avocado I.3 ~55 to ~87 Orange I.4 ~80 to ~123 BellPepper I.5 ~115 to ~155 Cauliflower Head I.6 ~140 to ~207 Banana Bunch

TABLE Group II (rectangular product cross-section) Tray # Range ofProduct Width (mm) Example Product II.1 ~55 to ~75 Spaghetti Box II.2~75 to ~95 Cheese block II.3 ~95 to ~115 ½ Gallon Juice II.4 ~115 to~145 Bag of Flour II.5 ~145 to ~195 Gallon of Milk II.6 ~195 to ~300Frozen Pizza

As previously described, embodiments may employ sensing ofcharacteristics of products that are stored in the carousel, in order toensure delivery at predetermined levels of freshness. One way that thiscan be done is by product imaging.

Specifically, optical characteristics of specific products at specificstages of freshness can be taken and recorded, in order to provide onemethod of quality measurement. FIG. 30 shows a simplified view of suchan approach, where a series of optical images 3000 a-e have been takenof a product (here a bunch of bananas) at different stage of itsfreshness lifetime, ranging from as harvested, to pre-ripe (e.g. green),to ripe, and then to over-ripeness (e.g., suited for banana bread), andfinally to no longer consumable.

Various optical characteristics of the image may be measured for eachpicture and stored, and a database created from the measurements.Exemplary optical characteristics which can be sampled by imagingaccording to embodiments, can include one or more of the following colorproperties:

-   -   hue;    -   saturation; and/or    -   brightness.

Using machine learning techniques in combination with artificialintelligence (AI) approaches, these images taken of produce along itsfreshness lifecycle, can be automatically segregated into qualitygroupings, depending upon how their optical properties (e.g., colors)change over time.

In one example, thirty-eight (38) images were taken of the specificbunch of bananas over its freshness lifetime. Saturation color propertydata for pixels of each of these images was sorted into 16 bins. Then,over ten iterations of K-means clustering, the resulting five groupingsof product quality in FIG. 30 emerged.

FIG. 31 is a resulting histogram of the saturation data, showing afraction of pixels exhibiting different values. By referencing suchcolor properties stored in a database in connection with additionalimages that are acquired of new incoming produce, embodiments canimmediately and accurately assign a freshness category to that incomingproduce.

In summary: calculating one or more color properties of pixels invarious optical images of a perishable product (such as produce), andthen using that color property data in order to develop a database, canprovide a model of the typical freshness life cycle of that produce.Such approaches would allow future color measurements to accuratelypredict a current status of newly-received instances of that perishableproduct during its freshness lifecycle (e.g., from harvested, topre-ripe, to ripe, to over-ripe, to no longer useable).

It is noted that the freshness correlation just described above, is notlimited to being based upon the sensed optical property of saturation.Other pixel optical data (such as from hyperspectral or multi-spectralimaging) can be referenced in the database.

Moreover, freshness prediction need not be based exclusively upon sensedoptical characteristics. To enhance accuracy of the product freshnessmodel and database, other factors could also be correlated within thedatabase with the product and considered, including but not limited toone or more of:

-   -   diameter;    -   length/width/height (LWH);    -   weight;    -   shape;    -   blemish count;    -   blemish size;    -   detection of the presence of mold or insects;    -   elapsed time from harvesting;    -   firmness;    -   texture;    -   sugar content;

In addition to the inspection data mentioned above, data incoming withthe product item from the source, could also be included in the databaseand correlated with expected freshness and other AI procedures. Examplesof such incoming data types can include but are not limited to:

-   -   source (e.g., grower);    -   location (e.g., orchard #);    -   heat treatments;    -   radiation treatments;    -   pesticides;    -   organic certification;    -   Genetically Modified Organism (GMO);    -   days of sunshine;    -   days of rain;    -   harvest date;    -   days in storage;    -   transport company;    -   transport type;    -   transport conditions (e.g., temperature, duration); and    -   time processed.

One or more of the data types described above, may be further correlatedwith product item data that is also stored in the database. Examples ofsuch product item data can include:

-   -   unique product item identifier;    -   Stock Keeping Unit (SKU);    -   locations (including past locations) of the specific product        item within the product handling system (e.g., by carousel,        tray, tray row, row position);    -   textual descriptor (e.g., “golden delicious apple”);    -   product classification (e.g., according to taxonomies set forth        by international/national regulatory bodies, such as Import &        Export);    -   brand name;    -   varietal;    -   vintage;    -   special notices (e.g., potentially allergenic, citations to        federal/state/local regulation—e.g., Food & Drug -FDA,        Agricultural—USDA);    -   association with other product items (e.g., by incoming        shipment, by recipe, by meal kit, others);    -   packaging status (e.g., none/loose, paper packaging, plastic        packaging, vacuum packaging, modified atmosphere packaging);    -   recommended shelf life.

One or more of the data types described above, may be further correlatedwith customer data that is also stored in the database. Examples of suchcustomer data can include but are not limited to:

-   -   dynamic pricing data (e.g., per-quality pricing, coupons, bulk        discounts);    -   data of product image offered to customer as part of selection        process;    -   user feedback;    -   producer preferences;    -   repeat ordering trends;    -   temporal ordering trends (e.g., time of day, seasonal, annual,        holiday, others);    -   customer location;    -   customer diets;    -   customer menus;    -   customer health (e.g., allergies);    -   inventory of items already available in customer's home.

One or more of the data types just described may be further correlatedwith system data that is also stored in the database. Examples of suchsystem data can include but are not limited to:

-   -   tray identifier;    -   row-within-tray identifier;    -   position-within-row identifier;    -   carousel identifier;    -   carousel storage condition(s);    -   bag identifier;    -   storage time;    -   dispense time;    -   inter-carousel transfer time(s).

Thus according to some embodiments, the database could be arelational-type database having rows corresponding to individualincoming product items that are being handled, and various columnscorresponding to different properties of that item (e.g., source,freshness state, carousel conditions, many others as mentioned herein).Such a database structure allows the data relevant to each handledproduct item to remain associated with that product over the entirelifetime of the handling process (e.g., from intake, through storage,retrieval, and final dispensing to the customer).

As mentioned above, embodiments may employ artificial intelligence (AI)and machine learning techniques—for example to assess product freshnessand predict future freshness based upon inspection and other data types.Such AI approaches involve a specialized procedure executed by aprocessor, which recognizes correlations between a corpus of knownstarting conditions and resulting historical outcomes. The specializedprocedure is trained and refined based upon the historical outcomes, andis then used to predict outcomes for new starting conditions notpreviously encountered (e.g., a new product being received for imaging).

FIG. 32 shows a simplified flow diagram illustrating a machine learningprocess 3200. At 3202, a training data corpus is selected. That trainingdata represents the various historical inputs, and the correspondingknown results.

At 3204, a model for predicting the results from the correspondinginputs is created. That model is mathematical in nature, and can be inthe form of weighted equations, neural nets, and others.

The model is configured to receive inputs in numerical form.Accordingly, at 3206 preprocessing is performed upon the various inputsof the training set, in order to convert them into numbers recognizableby the model. Such preprocessing can involve a variety of techniquessuch as normalization, tokenization, and others.

At 3208, the training data is applied to the model to refine itsstructure. In certain embodiments this training phase may involve theadjustment of weights within the model, to allow it to better reflectthe historical results that are produced from the known inputs. Thesemodel outputs are also in numerical form, and typically representlikelihoods of a plurality of outcomes. In this manner, the model istrained by the training data.

At 3210, a new input is applied to the model that has been trained bythe training data. In response, the trained model outputs a probabilitythat the new input corresponds to a particular outcome. This applicationof new data to the trained model is known as the inference phase.

At 3212, the numerical results output by the model are mapped intouseful information. For example, the mapping to an outcome may correlatea numerical result into to a particular product freshness state.

At 3214, the accuracy of the new predicted output can be evaluated. Thisevaluation of accuracy can then be fed back 3216 into the trainingcorpus to help further refine the accurate performance of the model inpredicting outcomes from new inputs. This new input is applied to themodel as trained by the training data.

FIG. 33 shows a simplified diagram illustrating the implementation ofartificial intelligence principles to product handling according toembodiments. System 3300 comprises imaging camera 3302 that performs anoptical inspection upon incoming perishable product 3304 (here anapple). That optical inspection may be for visible wavelengths, multiplewavelengths (multi-spectral imaging), or may include other than visiblewavelengths (hyperspectral imaging).

The optical data resulting from the optical inspection is stored indatabase 3306. As described previously, other data may also be stored inthe database, for example incoming product source and transportationdata 3308.

Based upon this stored data, an assessment of the physical state 3309 ofthe product may be produced by an inspection artificial intelligencemodel. That state may reveal blemishes or other features characteristicof product freshness (e.g., water content).

The product is then routed by automation control 3310 to a particularcarousel 3312 based upon considerations such as its freshness, expectedshelf life, and popularity. A separate AI degradation model 3314 maypredict the progression of the stored product through its freshnesslifecycle (e.g., as harvested, pre-ripe, ripe, overripe, not usable).This degradation model can ensure that only products of an accuratelypredicted freshness, are ultimately dispensed to the customer accordingto his or her preferences.

In particular, FIG. 33 also shows a customer input 3320 received by afulfillment engine 3322. The engine processes the input, and in responsecauses the carousel to dispense the product at its known state offreshness according to the AI model. As described above, the fulfillmentengine may utilize data including learning feedback 3324 (e.g., from thecustomer) in order to enhance the accuracy of this product dispensingprocess.

As described herein, artificial intelligence and machine learningapproaches may prove useful in predicting a number of different type ofoutcomes in the overall product handling process. One example is usingautomated quality prediction procedures and models in order to separateStock Keeping Units (SKUs) into quality groups that a consumer canselect from between based upon their preferences. Actual images of theindividual items may be offered to the customer during this productselection process.

Artificial intelligence and machine learning approaches may also beutilized in connection with dynamic pricing of specific items. That is,automated quality prediction procedures and models can be used todynamically price each individual item based upon properties such asfreshness, expected expiration, and demand.

Automated quality prediction models may also be referenced in order torank the individual product items belonging to a SKU, by their ripenessand expiration dates.

In summary, the following table lists several AI models, together withtheir expected inputs and outputs.

AI Model Input Output Inspection Optical data Product Blemishes Otherinspection data (e.g., detection Product Water Content of mold,ethylene, etc.) Freshness Optical Product Freshness State LifecycleProduct Blemishes Expiration Date Source/Transport data Other inspectiondata (e.g., detection of mold, ethylene, etc.) Product Pricing FreshnessState Dynamic Product Price Customer Data Product Ranking MultipleProduct SKUs Multiple Product SKUs Multiple Product Freshness StatesGrouped by Freshness State Product Storage Freshness State Location ofProduct for Storage Conditions storage in Carousel and Other StorageFactors (e.g., Tray of Product Handling allergies, typical purchase withother System products) Popularity (e.g., possible bottlenecks) ExpectedDepth Location in Bag Product Dispensing Freshness State Bag forReceiving Product Ranking Dispensed Product Customer PreferencesExpected Depth Location in Bag

Successful application of various such AI approaches may help to ensurethat a product exhibiting the quality desired by a customer, can berapidly and efficiently delivered to that customer. For example, theconsumer may be offered his or her selection of SKUs in a way thatallows the customer to always consume the item at peak ripeness. Thiscan lead to increased customer satisfaction.

Product handling systems according to embodiments, may provide thecustomer with the ability to purchase a set of individual product itemsbelonging to a particular SKU, with each individual item turning ripe onthe day requested by the customer.

Embodiments may also provide the customer with the ability to purchaseindividual product items belonging to a complementary set of SKUs. Thatis, items belonging to certain SKUs may commonly be purchased together(e.g., cake ingredients), and the system facilitates handling anddelivery of a set of those SKU items together.

Embodiments also allow for dynamic pricing of handled items. Bygenerating and storing in the database an up-to-date and accurateassessment of product quality and expiration date for each item, theitems can be dynamically priced for sale. For example, aging producehaving an earlier expiration date can be dynamically priced at a lowervalue, allowing for more rapid sale and product turnover, and reducingwaste.

Product handling approaches according to embodiments can exhibitincreased efficiency and flexibility in other ways. For example, thelarge number of data types stored in the database and available tovarious AI models, can permit automatic filtering of a consumer'sproduct choices or meal kit choices. This filtering can be based uponstored factors such as consumer diets, consumer allergies, and currentavailability of bulk items in stock at a consumer's home.

As described above, product handling methods and apparatuses accordingto embodiments, may be particularly useful for delivering perishableitems. In some embodiments the shelf life of a product may be measuredin days, for example in the case of fresh produce. Other products mayhave lifespans that are significantly longer than a week, for examplepre-packaged products or aged items such as cheese and wine. Examples ofproduct lifespans may be accommodated according to embodiments are 1day, 2 days, 3 days, 4 days, 5 days, 6 days, 1 week, 2 weeks, 1 month, 6months, 1 year, and 5 years.

While the above description has focused upon the handling and storage ofperishable items, embodiments are not limited to such examples.Alternative embodiments can store non-perishable goods, e.g., thoseexpected to have lifetime of five years or greater.

Further details regarding the inspection of products to determinedefects, are now described. Embodiments may use machine learning incombination with inspection to detect defects in produce based on theirarea and defect type.

There are at least two ways to inspect for defects. A first approachinvolves developing a model for each variety of produce. This amounts toaround 700 different models.

An alternative approach develops a universal model for each defect.Examples of such universal models could comprise a bruise model and acut skin model. This defect-based approach results in only about 40models being needed, reducing development time and enhancing robustness.

Specifically, utilizing visual/near-infrared imaging in combination withmachine learning, allows object detection for product item quality.Camera systems are used to take images of produce in a controlledlighting environment.

The images cover wavelengths in the visible RGB range as well as in thenear infrared (NIR) wavelength range. This can be accomplished withmultiple cameras (e.g. one RGB camera and one NIR camera), or a singlemulti-channel camera.

Specific filters can be added to the cameras to focus the inspection ona particular band of wavelengths, especially for the NIR camera. Each ofthe image modalities may reveal different types of defects on produce.For example, FIGS. 34A-B show NIR images, and FIGS. 34C-D show RGBimages.

The acquired images are labeled, and then used to train machine learningmodels to detect defect(s) that may be present. The models can betrained in at least two different ways.

According to one approach, a model is trained to detect all possiblekinds of defects on a single type of item (e.g., apples), by using atraining set comprising known defects on a series of images taken ofthat one item type.

According to another approach, a model is trained to detect a specificdefect (e.g., a bruise) across many types of produce (e.g. as found onapples, pears, tomatoes, peaches, etc.) using a training set comprisingimages including the specific defect on a variety of produce types.

The object-detection type model is one possible example. Here, theRetinaNet deep learning algorithm was adapted for this purpose. The sizeof the resulting bounding box around the detected defect, indicates thesize of the defect.

The resulting information on differentiated defects in the images, andthe size of each defect, is combined with a produce-specific algorithmto determine a quality grading for the item.

Moreover, this information can also be combined with other information(including harvest date, prior storage conditions, future storageconditions, etc.) in a procedure which predicts how the produce willripen or degrade over time.

While the above has described inspection of items utilizing a camera,this is not required. As an alternative or supplement to a camera, aspectrometer may also be used.

Specifically, spectrometer measurements (e.g., reflection, absorbance,transmission, etc.) of an item in the VIS/NIR wavelength range(˜350-2500 nm), permits analysis of the external/internal properties ofthe item, which can include but are not limited to:

-   -   color;    -   external defects;    -   internal browning;    -   dry matter content;    -   sugar content;    -   firmness;    -   rot; and    -   others.

In one implementation, portable spectrometers have been developed foragricultural applications in inspecting produce before picking, or forlater handheld inspection of individual pieces of produce.

An embodiment of a process according to a particular example, may takespectrometer VIS/NIR measurements of incoming produce items. Thatspectrometer data may be correlated with quality, defects, and currentripeness level of produce. FIG. 35 shows a simplified spectrograph.

The spectrometer ripeness prediction is combined with data from othercamera inspection systems and historical information on produce (e.g.,date picked, variety, growing location, previous storage conditions,storage conditions while in grocery store). This data may be used toassess optimal time to deliver produce to customer and predict timelinefor how produce will ripen and/or decay while in the grocery store. Thisapproach reduces waste, improves operations/logistics, and improvescustomer satisfaction.

Products may be inspected prior to entering storage in the carousel(s).Product lifetime may be estimated based upon the inspection results.

In some embodiments, however, products can be automatically inspectedafter storage, either exclusively or in combination with inspectionprior to storage. Such post-storage inspection can employ one or more ofthe following techniques.

Cameras may be used to inspect a full tray or products directly afterbeing pulled from the carousel. Cameras may also inspect individualproducts after they are removed from a tray and before they aredispensed into a bag.

Moreover, sensors other than visual sensors (e.g., cameras) may beemployed to inspect the products. For example, berries degrade quicklyby getting moldy—a negative experience for the customer.

It is possible to sense mold by “sniffing” the gas around the product.In once embodiment, a nozzle could just be positioned to suck air frominside a clamshell enclosing a berry. The sampled air could then beanalyzed. In another approach each case could go through a closed boxwhere the air is analyzed for mold spores.

Details regarding apparatuses that may be utilized for productinspection, are now provided. A variety of methods may flip and/or spinproduct items during camera inspections to allow interrogation frommultiple sides.

Product item shapes may be generally classified into spheres, cylinders,and cuboids. After inspection, the items are sorted into trays based onvarious criteria. A number of approaches may be used to place items ontotrays as part of intake, inspection, and/or sorting of individual uniqueproduct items incoming to the system.

One approach utilizes a pivoting belt conveyor. FIGS. 36A-B showperspective views of a single conveyor having a linkage that can beangled from flat over a range of angles.

Items can translate through the conveyor. FIGS. 37A-F show simplifiedviews of pivoting belt conveyor flows.

Spheres and cylinders will roll when the conveyor is rotated up at anangle. This is shown in FIGS. 37A-C.

Also, the unit can fold over itself in order to flip a box item. This isshown in FIGS. 37D-F.

It is noted that two O-ring belt conveyors can convey almost all items.And, cameras from 6 directions take images of the items. FIGS. 38A-Dshow various views of an embodiment of such a simple convey withmultiple cameras approach. Using six cameras as shown, all sides of theitem can be imaged quickly.

Certain approaches may utilize free fall imaging of items. That is, asitems fall off of a conveyor, they are imaged in the air. FIGS. 39A-Bshow different views of such an approach.

Multiple cameras capture all sides of the items. The item is caught witha cushioned conveyor or other soft landing pad, before moving theproduce further along the conveyor. This method allows for quick imagecapture of all sides of an item, without having to deal with otherhardware being in the camera field of view. This permits a singlemachine learning model to be used with the images taken from allcameras.

Another possible approach utilizes a star wheel conveyor, as shown inFIG. 40. The star wheel conveyor is a multi-arm conveyor that canrotate. FIGS. 40A-C show simplified views illustrating that spheres andcylinders can be rotated as the conveyor belt runs. When in the 12o'clock position, the item can be imaged while rotated.

Cuboid items can be flipped when going through the system. This is shownin FIGS. 40D-F.

Such a star wheel conveyor allows many items to be completely imagedwith a limited number of cameras. The cameras may have the samemechanical components in the FOV, which simplifies the machine learning.

Still another approach may utilize a popup roller conveyor. FIG. 41Ashows a top view, and FIGS. 41B-C show end views of such a mechanism.

According to this approach, two o-ring belts convey items in the store.The rollers pop up next to the conveyor when the item is in place.Cylinders and spheres are rolled along the conveyor, thereby presentingall sides of the item to a few cameras. Different size rollers may beused based on the item size.

This system allows for a majority of items to be fully imaged with alimited number of limited cameras. The cameras may have the samemechanical components in the FOV, which simplifies the machine learningstrategies.

Another mechanism that may be useful for handling items within thesystem, is a roller and spinner conveyor. FIG. 42A shows a top view, andFIGS. 42B-C show perspective end views of an embodiment utilizing thisapproach.

Here, the conveyor comprises trapezoidal rollers, and items are carriedalong by the conveyor. The roller/spinner conveyor stops and the rollersspin, thereby rolling cylinders and spheres. Again, this action allowssides of the item to be presented to only a few cameras. The cameraswill have the same mechanical components in the FOV, which simplifiesthe machine learning.

FIGS. 43A-45C show other possible approaches for handling items forpositioning onto a tray. These methods, described below, can be utilizedalone or in various combinations.

A pop through conveyor offers a possible approach for item handling.FIGS. 43A-B illustrate top and side views, respectively, of such amechanism. Here, the tray moves left and right while pop throughconveyors advance items along a belt.

Specifically, this concept provides an auto tray loading concept that issimilar to the dispense station. Two belt conveyors distribute the itemsalong the length of each row. The tray moves so the items are located inthe correct row. This approach allows items of different grades to beseparated in their distinct row of the tray, without requiring a buffersystem or unique classification separation system.

Still another item handling approach may utilize an XYZ gantrymechanism. FIGS. 44A and 44B show simplified top and side viewsrespectively, of an embodiment according to this approach. In thesefigures the tray moves left and right and in and out. The item feeddrops item into the tray.

Here, the trays are disposed on a moveable XYZ gantry, and move the trayto a distinct position so the item may be placed in the exact positiondesired. This concept allows items of different grades to be separatedin their distinct row of the tray without needing a buffer system orunique classification separation system.

Still other item handling approaches may utilize a vertical stack buffersystem. FIG. 45A shows a side view, and FIGS. 45B-C show top views,illustrating an embodiment.

Specifically, this approach offers a post-inspection, pre-tray loadinggrade and size filtering system, allowing items of the same grade and/orsize to be are grouped together. This mechanism allows for a simplertray loading mechanism as all items are filtered into the correctcategory, prior to being taken to the tray loader.

In the specific approach illustrated in these figures, there is avertical buffer that builds each row. So, the infeed becomes morecomplex, moving up and down and left to right to feed a fixed trayposition.

As shown in the top view of FIG. 45C, the conveyor branches to allowFirst In, First Out (FIFO) filtering amongst each branch. Each branchcontains the same size and/or grade.

This multiple conveyor setup shown in FIG. 45C, allows for a simplertray stocking mechanism, as all items are filtered into the correctcategory prior to being taken to the tray loader. This embodiment alsooffers relative simplicity from a mechanical perspective.

As has been previously discussed, embodiments may call for items to bestored under controlled conditions, in a carousel structure. Variousaspects of possible designs for the carousel element, are now described.

Initially, it is noted that trays can be shifted from one carousel toanother. This may be done automatically in order to control ripeness.

For example, an avocado should be initially stored in a cold carousel inorder to preserve its life. Then, a few days prior to being dispensed,the avocado should be shifted to a different carousel that is maintainedunder warmer temperature conditions, and paired next to an ethyleneproducing item. This will initiate ripening.

Once the ripening process has commenced, the avocado could be shiftedback to a colder carousel to keep it from over-ripening. The avocado canthen be sold to a consumer at the desired ripeness. Such acarousel-shifting approach allows more products to be stored ininventory, without spoilage and loss of desirable characteristics (e.g.,flavor and nutrients in the case of a produce item).

FIG. 46 shows a simplified perspective view of a front of a carouselaccording to an embodiment. As previously illustrated, items are storedwithin the carousel upon moveable (e.g., vertically moveable) carriers.

FIG. 46A illustrates a perspective view of one possible embodiment of acarrier. This carrier embodiment features lower support beams.

FIG. 46B illustrates a perspective view of an alternative embodiment ofa carrier. Here, the lower supports are replaced with backside supportbeam(s). Such a back-support approach may effectively increase thedensity of items that may be stored within the carousel.

Specifically, by avoiding the space occupied by a bottom support beam, acarrier design can fit 7, 6, 5, or 4 shelves. Carriers of variouscapacities may be available in each carousel, as needed.

FIG. 46C shows a simplified front view of a carrier. Here, two 3 mm backsupport beams take most of the load, and transfer to outer supportwalls. The back beams support vertical load, and resistdeflection/twisting.

Extending out of the page in FIG. 46C, is a single part featuring tabsto hold trays. By eliminating the bottom supports (and increased backsupport) this embodiment affords enhanced vertical tray stackingdensity—according to some embodiments thereby allowing one more fulllayer of trays per carrier. Particular embodiments may offer 10.2% moreproduct storage because of the back (rather than bottom) support design.

Various configurations may further enhance densities of verticallystacked trays within a carousel. For example, while the specificembodiment of FIG. 46B offers support for multi-layers for trays with afixed pitch, that pitch may not be optimal for all items.

Different types of carriers may be present in each carousel. Eachcarrier can be constructed to handle different level counts in order tomaximize density.

For example, FIG. 46D shows carriers having a different number oflevels, and per-level pitches, to allow storage of different items. Asshown in FIG. 46D:

-   -   a carrier having 4 levels might offer a greatest stacking        density for trays storing honey dew melons and 2 gallon milk        jugs.    -   a carrier having 5 levels, might offer a greatest stacking        density for trays storing green peppers and mayonnaise jars    -   a carrier having 6 levels, might offer a greatest stacking        density for trays storing oranges and pasta boxes.    -   a carrier having 7 levels, might offer a greatest stacking        density for trays storing apples and rice boxes    -   a carrier having 8 levels, might offer a greatest stacking        density for trays storing limes and salad dressing bottles.

Once items are stored within the carousel upon a tray supported by acarrier, individual items may be dispensed therefrom. Various detailsregarding particular embodiments of dispensing mechanism are nowdescribed.

FIG. 47 shows a perspective view of a front side of a carousel, havingattached thereto a dispensing station according to an embodiment. Theview of FIG. 47 may usefully be contrasted with the previous view ofFIG. 46.

An item dispensing station according to embodiments may feature one ormore elements to enhance performance. For example, it is important toavoid items falling off the dispense station. Accordingly, certainembodiments may feature a dispense conveyor backstop on the pop throughconveyor, in order to keep items from falling backwards.

FIG. 48A shows an enlarged view of a tail on the conveyor, whichprevents items from rolling off the back when the tray is lowered overit and items from a row are dispensed. FIG. 48B shows a simplifiedperspective view of the pop-through conveyor of the dispense station,poised to dispense item(s) from a particular tray row.

Dispense stations according to embodiments may also feature sensors fordetecting dispensed items. FIG. 49A shows a side view of a pop-upconveyor mechanism including an optical sensor for dispensed itemdetection. FIG. 49B shows an enlarged view of the optical sensor in thepop-up conveyor.

This presence sensor detects when an item arrives at the end of theconveyor. The length of the item is already known, so once the item isdetected the conveyor can be driven the known amount to dispense theitem off of the conveyor end. The sensor also detects that the item hasleft the conveyor, thereby allowing reliable confirmation of dispensinga single item.

Weight can also be detected as a sensed quantity during dispensing. FIG.50 shows a perspective view of a dispense station configured with loadcells for this purpose.

Load cells may permit weight measurement to detect items falling off thedispense station (e.g., off of the back). Load cells can also be used todetect the change in weight as an item leaves the conveyor.

Load cells may be positioned in a number of different possiblelocations, including but not limited to:

-   -   under the mounting rails for the mobile platform;    -   on the extending conveyor rail; and/or    -   at a strain gauge between the end rollers.

As an item is dispensed off the end of the conveyor, the load cellreading marks a step change, indicating the reduction in mass on theconveyor. This again permits reliable dispensing of just one item at atime from the tray.

In order to accurately accomplish item dispensing in a reliable manner,it may be useful to precisely control tray position. Maintainingpositional control of the tray within a tolerance, allows the dispenseconveyors to repeatedly fit through the slots in the tray, whilereducing the layers of closed loop motion control.

The exercise of positional control over the tray may commence when thetray arrives at the carousel (FIG. 51A), and is then loaded into thecarousel (FIG. 51B). From the time the tray is initially physicallycontacted, it is passed from pinned location to pinned location.

FIG. 51C shows a simplified view of the use of indexing pins.Specifically, the tray lifter aligns with the tray and lifts it up withthe end effector. These end effectors on the tray lifters inserting andremoving the tray from the carousel, have pins that index with the tray.

The carrier has pins that index with the tray. The tray arrives at theupper tray lifter and is lifted by the end effector. The end effectorpins index with the tray, locating it precisely. The upper tray lifterinserts the tray into the carrier, where it also indexes on pins. Usingsuch passive (e.g., pin) features to control position of the tray duringstorage, allows for closer tolerances on the dispensing end effectorwhile still allowing retrieval without closing the loop between the endeffector position and the tray position.

Exercising positional control of the tray on the end effector, alsopermits precise disposition of the dispensing conveyors so they fitthrough the slots in the tray without closing the loop between trayposition and dispensing conveyor position.

Details regarding designs for the end effector are now described. It wasdiscovered that reaching relatively deep into a narrow space called forbetter control over the angle of the end effector, than:

-   -   reaching into a short space, or    -   not reaching in at all, and just hooking the front end of the        tray.

Accordingly, FIG. 52A illustrates a simplified side view of an endeffector design according to one embodiment. Here, using injectionmolded parts for the trays allowed for a simplification in the carrier.The shelf upon which the tray sits, was made flat rather than a U-shape,in order to dodge the tray lifter linear slides.

FIG. 52B shows an alternative embodiment wherein the end effector on thetray lifter, is a hook that engages with the front edge of the tray. Thetray is pushed into or pulled out of the carrier, by the hook endeffector.

The tray slides on the carrier shelf and also slides on a shelf on thetray lifter. This eliminates the issue of leveling the carriers to thetray lifter and maintaining level tolerance for every carrier in everyloaded state.

FIG. 52C shows another alternative embodiment. Here, the end effector onthe tray lifter may have a pinion gear that engages with a rack (whichmay be molded into the tray). Driving the pinion gear pulls the tray outof the carrier and onto the tray lifter. This eliminates the problem ofleveling the carriers to the tray lifter, and maintaining a tight leveltolerance for every carrier in every loaded state.

FIGS. 53A-B show different views of carrier design embodimentsconfigured to interact with the end effectors of FIGS. 52B-C. Here, withthe new hook design or gear rack design, the slides do not have toinsert into the carrier.

This allows for increasing the pitch of the carrier shelves receivingthe tray. Such increased shelf pitch promotes an increase in traypacking density, by allowing choice of the best shelf to put the tray onto allow it to be closest to the next tray above or below.

It is noted that the slides holding the end effector need to fit betweenthe shelves. Not needing to preserve open space for slides, allows theshelf pitch to be tighter. The tray can be positioned closer to the oneabove or below it depending on the height of items in the tray.

Details regarding various designs for the customer bag and thetransporting same for shipping, are now discussed.

A traveler containing a bag to receive dispensed items, may feature aplatform that can be raised and lowered. There are several possible waysto raise and lower the platform.

FIG. 54A shows a perspective view of one embodiment of a traveler. Inthis embodiment, the traveler platform may be moved up and down throughthe operation of lead screws that are driven by a chain or belt.

FIG. 54B shows an alternative embodiment of a traveler. Here, theplatform may be raised or lowered utilizing linear actuator(s), andguide rail(s) located in opposite corners.

Alternative designs for travelers are of course possible. Certainembodiments could feature the platform attached to a scissor lift. Someembodiments could feature the platform lifted in corners by belts orpulleys. Also, a traveler design could comprise an assembly of springsthat compress when the bag is full, and extend when the bag is empty.

Some embodiments may add load cell(s) to the platform, allowingmeasurement of changes in weight at the traveler. FIGS. 55A-B show viewsof an embodiment of a traveler incorporating load cells.

In this embodiment, the load platform comprises two plates. The bottomplate is anchored to lead nuts that travel up and down the screws.

Four cantilever beam load cells support the top plate. These load cellsmeasure the weight of items in the bag, helping to determine if itemswere successfully dispensed.

While the specific configuration of load cell may vary, the basicconcept features the measurement of weight changes to evaluatedispensing. Given known item weights, with proper calibration thedifference between weight changes (e.g., 1 apple vs. 2 apples) canreveal when possible errors occur.

Bag(s) for housing items dispensed from the carousel, are supported bythe traveler. One or more methods may be utilized to hold the bag inplace at the top of the frame.

FIGS. 56A-B show top perspective, and enlarged views respectively, of atraveler including a frame. Bags are first bunched or accordioned,around a rectangular box for quick loading into the traveler. Thisrestrains fabric to the perimeter of the bag, thereby leaving the bagbottom exposed to receive the dispensed item, without interference frombunched fabric.

According to particular embodiments, the bags may have fabric grommetsinstalled in their upper corners. Bags are loaded into the traveler byhooking the grommets over bent pegs located in the upper corners of theframe.

A hinged lid (with an integrated latch) opens and closes to lock the bagin place. The inner rim of the lid may be lined with bulb edge guards toprotect dispensed items from being damaged.

However, alternative designs for the traveler are possible, with the bagbeing fixed according to other approaches. For example, FIG. 57A shows atraveler embodiment featuring straight vertical grommet pegs, stickingup. An (optional) removable rubber cap may be tethered to the bottom ofthe peg, for a quick locking feature with a part that doesn't get lost.

FIG. 57B shows an alternative traveler embodiment featuring straightvertical grommet pegs, sticking down, embedded in the lid. When closed,the pegs insert into holes, locking the bag in place.

Still further alternative traveler designs are possible. Someembodiments may feature a quick turn arm and locking post. Otherembodiments may include velcro tabs sewn on to the upper bag corners.Magnets could also be used as clamps.

FIGS. 58A-B show simplified views of a plunger and grommet, and travelerembodiment incorporating same. Here, pop-out panel fastening plungersare installed in bag rim to lock into place. A loop of sheet metal wrapsaround grommet and bag fabric, clamping the bag in place.

A traveler according to an embodiment may feature a frame topped with ahinged lid. FIGS. 59A-C show simplified views of a hinged lid. Theenlarged view of FIG. 59C shows the T-profile hinge integrated intosheet metal, locked in place after initial assembly by installing ablock covering the wide slot. FIGS. 60A-B are perspective views of atraveler showing the hinge and spring clasp, with the lid open andclosed, respectively.

According to certain embodiments, the traveler may be powered by aquick-swappable battery pack design that can be easily replaced forcharging. The battery pack may comprise a housing and two sealed leadacid batteries wired in series inside the housing.

FIG. 61A shows a battery pack embodiment with the power plug located inthe back of the housing relative to the front flange. FIG. 61B shows abattery pack embodiment with the power plug located on the side of thehousing relative to the front flange.

A processor can measure the battery's state of charge by reading itsvoltage. When the battery pack is low on charge, it can be removed fromthe traveler base without tools. It may be unplugged without any loosewires; the power plug and jack are embedded in the traveler base andbattery pack housing, respectively.

The battery pack may be charged in a parallel rack system located closeto the bag unloading station. A fully charged battery can be loaded intothe traveler so it can continue its work with only a short interruption.

As noted previously, particular embodiments may afford movement of thetraveler based on conveyor action. FIG. 62 is a simplified view showingconveyors 6200 can stop tray 6201 in front of an individual stagingposition 6202, to receive item(s) 6204 dispensed from a given carousel6206.

In particular embodiments, the conveyor system for the traveler maycomprise a collection of modular conveyor sections and 90° transferstations. This conveyor system moves the travelers around thefulfillment center to accomplish their tasks (e.g., receiving dispenseditems, possibly loading trays into carousels).

The conveyors may be arranged in grids and loops. Each section iscapable of running in both forward and reverse directions.

According to embodiments, each conveyor section is an independentlycontrolled set of rollers linked together with drive O-rings. One rollerpin in each conveyor section has an integrated motor with servo controlthat allows precise positioning of a traveler on that section, in thedimension of conveyance (e.g., across the dispensing station located atthe front of the carousel).

Position control along this dimension, combined with position control ofthe dispense arms of the tray lifter in a perpendicular dimension,allows items to be dispensed to precise locations in the bag.

When a traveler is supported by rollers of adjacent conveyor sections,control software may instruct coordinated movement of both conveyorsuntil the traveler is fully in control of the downstream section. Atthat point, the section can move the traveler around without affectingthe positions of other travelers.

This independent control can facilitate precise item dispensing at everydispense station. A photoelectric sensor may be integrated in eachconveyor section to trigger a reference position of the traveler as itmoves onto the section.

Different variations on the design and operation of the travelercomponent, could serve to enhance system operation. For example, incertain embodiments the traveler may include its own drive system (e.g.,wheels, tracks, rails, others) and/or sensors (e.g., cameras,line-following optics) that permit autonomous or semi-autonomousmovement throughout the fulfillment center.

Certain embodiments may feature the addition of duplicate bag lockingmechanisms. These could allow each traveler to carry multiple bags atonce.

It is noted that a single traveler could fulfill a single order,multiple orders, or parts of separate orders, during various tripsaround the fulfillment center. This can lead to enhanced efficiency.

Certain embodiments may feature the addition of a tray-carryingattachment to the traveler. This would allow the traveler to bring traysto each carousel for loading. Such integration of tray loading and itemdispensing with a common moveable structure (the traveler), would leadto substantially simplified operation.

Some embodiments could feature the addition of a high speed actuatorcapable of moving the load platform downward at high speed. Suchnear-matching the downward projectile velocity of a dropped item coulddesirably reduce impact forces on the item and upon the load platform.

Some specific details regarding design and operation of trays accordingto particular embodiments, are now provided. Trays may be fabricatedutilizing an injection molding approach that ensures high strength.

According to certain embodiments, the entire tray may be created as asingle, unitary injection-molded piece. FIG. 63A shows an end view of atray that is configured to hold circular items.

Here, the largest outer diameter (OD) of a stored item, matches pitch.The smallest OD is determined by a center of a round cross-section nottipping past hump on the center beam of the tray.

The strength of the center beam is dependent upon height. This reducespacking density in the carousel. The base may be widened with ribs inorder to resist side loads

FIG. 63B shows an end view of a tray configured to hold cuboid items.Boxes may also fix in the same rows and rounds. As width of stored itemsincreases, items start to rest upon the lips of side walls. This servesto spread the load while keeping smaller boxes under belts. Conveyorbelts of the dispensing station go up through same position, dependingon tray type and item type (e.g., round vs cuboid). Belts are designedto ensure contact with the smallest allowable box item of a given traytype.

FIG. 64 shows a top view of a tray according to an embodiment. Bumpsstop items from traveling past the curve of the belt. Holes molded infor indexing to the carousel and to the dispense station. Crossing websto add additional support and torsional resistance Webs in outer beam,align with inner beam walls in order to reduce wall deformation.

Reliance upon a single, unitary tray design, can increase manufacturingcost. Moreover, the resulting fixed size of tray features (e.g., numberof rows, width of rows, number and shape of separators) can limitflexibility and degrade efficiency.

Accordingly, alternative embodiments may feature a design that allowsdifferent tray types to be assembled from a plurality of injectionmolded parts. FIG. 65A shows a perspective view of one tray type, andFIG. 65B shows a perspective view of another tray type, that may beassembled from a plurality of parts.

The enlarged tray views of FIGS. 66A-B show 2 types of support beams.One type has mates on both sides. Center beams clip into the supportbeams. There are 4 types of center beams, with a center separation beambeing of one type.

FIGS. 67A-B are enlarged views showing tray features formed frommultiple molds. In particular, the view of FIG. 67A shows the supportbeam fitting over the side beam. Key features keep parts from turning atthe bottom. The view of FIG. 67B shows a pin poking through 4 tabs,bending them back, and locking the pin vertically.

In some embodiments, trays having various different features may beassembled on demand. Equipment may be designed to accomplish this trayassembly process.

Specifically, item handling systems according to embodiments may utilizea fixed number (e.g. 10) of tray types. Each tray type may hold acertain size of item.

Individual trays may comprise a plurality of parts in the form of long,narrow, injection molded pieces that clip together to form a tray.

Following item inspection, the tray loading station needs to receive anappropriate tray type to load the inspected item into.

Rather than store stacks of trays of each type, a machine may access theindividual pieces stored sorted according to type. Then, on demand, themachine may then assemble a tray of a certain size.

It is noted that the unassembled pieces have a higher storage densitythan the assembled tray. Thus, on-demand tray assembly can save valuablespace within the fulfillment facility.

According to embodiments, the machine could also assemble on-the-fly,trays in configurations other than the limited number of standard types.This could be done by building rows with different spacings, as calledfor by the tray loading station.

Empty trays removed from the carousel could be returned to the machine.There, the empty trays are automatically broken back down intoindividual pieces for efficient storage.

Such approaches featuring on-demand tray assembly, may offer one or morebenefits. As mentioned above, these approaches may save space on theline.

Also, on-demand tray assembly may allow for a larger variety of traystypes, and may decrease the distance a tray has to travel to get to thetray loading station if the machine can be located closer (potentialtime reduction).

On-demand tray assembly may reduce the total number of tray piece partsrequired. This is because trays can be reconfigured as necessary, ratherthan wasting tray inventory space on tray types that aren't beingutilized.

Returning now to discussion of general system operation, under somecircumstances it may be desired to dispense an item that is not locatedat the end of a tray row (e.g., is stored in the middle of the tray).Accordingly, certain embodiments may utilize a gantry robot fordispensing purposes, as is shown in the simplified view of FIG. 68.

For example, when each item in a SKU has a different value, it may bedesired to dispense from the center of a tray. Thus where the product isa steak, there may be 40 images of different cuts of steak that areavailable to show the customer for selection. By allowing a gantry toaccess center portions of the tray, all of the steak cuts can beavailable for dispensing.

Another possible circumstance that may be favorable to the use of agantry robot, is where the items are not amenable to conveyordispensing. This could be due, for example, to the items' size, shape,and weight. In such cases, a gantry robot may be a viable alternative.

Also, when items are small and thin (e.g., a gravy packet or beef jerkypouch), it would be advantageous to stack them vertically in one trayand then pick the top item from each tray. This increases density.

Finally, dispensing with a gantry robot could be useful when an item israrely purchased. Under such circumstances, it is inefficient to carryan entire row of that SKU. The use of a gantry robot to pick from thecenter of a tray, allows placement of multiple SKUs in one row, andpicking them out as needed.

It is further noted that a gantry robot could be employed in combinationwith a conveyor. Specifically, a gantry fixed at the end of conveyorbelt(s) could catch the item and lower it into the bag. This couldreduce damage to items.

Item handling systems according to embodiments, may not be limited to asingle physical location. Items may be dispensed and delivered frommultiple smaller sites that are located relatively close to one another(e.g., in different neighborhoods within a single large metropolitanarea.

Under such conditions, an inventory management solution may feature onecentral store (the hub) and many satellite stores (the spokes). Thisapproach could be implemented with tray packaging performed at the hub,and trays shipped to each spoke. Carrying racks could be designed toallow distribution vehicles to rapidly and easily perform loading,transport, and unloading.

In summary, FIG. 69 offers a simplified flow diagram of a processcontrol according to an embodiment. This flow diagram illustrates theinteraction between a central process and control system with variousphases of order fulfillment on the front end, and inventory managementon the back end.

A system according to various embodiments may include one or morefeatures to enhance automated dispensing and delivery of handled items.For example, in order to replace pallet jacks, robotic pallet jacks canbe utilized remove items from trucks that are delivering bulk goods forintake, inspection, sorting, and loading into carousels. Also, roboticssystems that can raise and lower pallets and insert into shelving, maybe relied upon to lift pallets onto shelves. Further, once a pallet isready for inspection, automation equipment may move boxes from pallets,and move the box contents onto a conveyor.

Moreover, particular embodiments may automate order packing as follows.When a full traveler arrives, equipment would lift a bag out of thetraveler and move it to a shipping area. Another piece of equipmentcould place a new bag into the traveler.

A robotic cart would be deployed to transport bags from the factory tothe parking lot. The robotic cart would place bags into the mode oftransportation for delivery.

A variety of delivery options are of course possible. Vehicles could bemanually driven by humans, or self-driven. Alternatives can includedelivery by bikes, carts, drones, or trucks plus drones.

It is noted that various embodiments may enhance a customer's experienceby allowing flexibility and choice in selecting items. A customer maysearch for items on a website utilizing a search bar.

Under this approach, the user enters a product name, and in response ispresented with a list of options. The customer selects an option, whichis added to the customer's cart. While the search bar approach is fastfor individual items, it can be laborious for a cart comprising multipleitems. Also, the search bar approach requires a customer to know desireditems in advance.

In contrast, with the search bar approach, an aisle-based approachinvolves a customer seeking a particular product item, to traverse acomplex hierarchy. Thus, a customer seeking to purchase a red onion, mayneed to:

-   -   click fruits and vegetables    -   click vegetables, then    -   scroll to find red onions.

Such an aisle-based approach takes longer than searching if a customerknows ahead of time what is desired. But, the aisle approach affords thecustomer the ability to browse different options, and get inspirationfor other products. However, aisle-based selection can be tedious due tothe many possible available options to scroll through in each aisle.

Accordingly, particular embodiments may permit customer searching foritems based upon categories. This approach can specifically leadcustomers to the particular items that they want to buy.

Under the category-based approach, a customer browses item categories,permitting visualization in a more useful manner. The categories wouldbegin as general, and then narrow to become more specific.

For example, FIG. 70 shows a simplified view of categories for fooditems that are organized into a tree hierarchy. Once the category“Pizza” is selected by a customer, the website offers a variety of itemsfor selection.

One possibility is to display for customer selection, standard pizzaoptions (e.g., pizza crust, sauce, cheese). Meat Lovers will add sausageand salami (for example). Such category-based searching can depictingredients going into making a pizza. So, this approach shows differenttypes of pizza dough (frozen, refrigerated, different brands), thesauces (bottled, cans, brands), different vegetables, etc.

Then, the user could (de)select one or more suggested items, removing orchanging the brand. Finally, the user could add to the cart all of theitems selected by category, and move on to a different category.

Over time, an engine of the system could learn preferences of specificusers/user groups, and suggest appropriate option the next time thepizza category is selected.

Embodiments may suggest ideas to a customer based upon machine learning.Embodiments could suggest specific items for purchase available in stockin large volumes.

Through the user of category-based searching, the consumer's experienceis more rapid and intuitive. For example, in shopping for grocery items,customers traditionally think in terms of item groups of meals andcategories, e.g.: “We need three dinners tonight, I need breakfast andlunch food for the week and I wanted to make that chocolate cake onWednesday for Sue to take to school”.

Here, the user can go to each category and select out their dinners in afew action steps (e.g., clicks). Similarly, a customer can select arecipe for the cake and obtain all the ingredients at once, or they canclick each ingredient from one basic list if they have a recipe.

In this manner, customers are free to select items in a more intuitivemanner, mirroring how they think and in terms of groups of items. Thusinstead of having to choose and select 30 separate items, they areselecting instead only 7:

-   -   3 dinners    -   2 lunch options    -   1 breakfast option    -   1 cake option.

Category-based selection can enhance the speed of purchase, movingcustomers through the site faster. Currently it can take around 60 minto fill a virtual shopping cart, a time comparable to (or even longerthan) physically going to a grocery store. Improving the check out timeis can aid in securing a steady on-line customer base.

Category-based item shopping can also enhance the flexibility of theseller. Grocery stores may seek to leverage relations between items byplacing them in physical proximity (e.g., salsa next to chips, marinadesby the meat counter). However, this is done in a crude, opportunisticmanner, constrained by available physical space (it is unfeasible toposition pizza sauce, veggies, pepperoni, and pizza dough, all in a sameaisle).

By contrast, a website offers a virtually unlimited variety of ways togroup related items to facilitate common purchase. Category-basedselection leverages this inherent advantage of web-based shopping, toenhance the user's experience.

FIG. 76 offers a simplified block diagram showing an overview of asystem according to an embodiment. Specifically, system 7600 comprises aplatform 7602 including a processing engine 7604 and a graphic userinterface 7606 in communication with a customer 7608.

The platform is in communication with a facility 7610 via acommunications network 7611. In particular, the engine is configured toprovide instructions 7612 to cause the facility to intake 7614 aplurality product items in bulk form, to perform an inspection 7616(e.g., utilizing camera 7617) of those bulk items, and to sort 7618those bulk items on the basis of the inspection.

Further on the basis of the inspection, the platform is furtherconfigured to instruct an apparatus 7620 to assemble trays 7622 fromindividual parts 7624 (e.g., injection molded pieces). The trays thenreceive the sorted product items, and are in turn loaded 7626 intocarousels 7628. As has been described extensively above, those carouselsare maintained under particular set(s) of environmental condition(s).

The platform is further in communication with non-transitorycomputer-readable storage medium 7630 having data stored thereon. Forexample, database 7632 may comprise data regarding various aspects ofthe system and the products stored therein.

Data stored in the database may be referenced by the platform to fulfill7633 a customer order. In particular, the customer may issue to theplatform, a request 7640 specifying a particular item type 7642 (e.g., aspecific apple varietal such as golden delicious). The platform mayreceive the request, and reference that item according to a tablestoring SKU information.

Then, with reference to data in the database, the platform may return todisplay to the customer in the GUI, data regarding a plurality of uniqueindividual product items 7644, 7646, and 7648 matching the request. Thedata may comprise specific information 7650 regarding those individualproduct items, including but not limited to an image, a lifetime, andothers.

Then, the GUI is configured to receive a user selection 7652 of one ofthe particular product items. In response, the engine is configured toinstruct a dispensing station 7653 of the facility to dispense thatunique individual item from the tray and carousel, into packaging 7654supported in a moveable traveler 7656.

While the particular embodiment shown in FIG. 76 depicts the routing ofproduct items directly from the dispensed carousel to a shipping stationfor delivery, this is not required. Alternative embodiments could employan intermediate carrier shuttle structure. There, items are dispensed tothe intermediate carrier shuttle, that is in turn brought to a differentlocation for consolidation of product items into packaging.

In some embodiments, it is noted that the processing engine maycommunicate to the facility, an instruction to transfer 7657 a productitem from one storage carousel to another. Such a transfer instructioncan be based upon considerations such as an expected ripeness of theproduct item, a storage capacity of a particular carousel, and anexpected future order of a product item (e.g., as may be predicted bymachine learning). This transfer can be accomplished utilizing atraveler (as shown), or alternatively utilizing a different systemcomponent.

According to certain embodiments, the product dispensing and/or transfermay be accompanied by an inspection 7680 (e.g., as performed by a camera7682). This dispensing/transfer inspection may be the same, or may bedifferent, from the original inspection forming the basis for theinitial sorting.

Finally, once all of the selected customer items have been collected inthe packaging, the engine is configured to instruct the traveler to movealong path 7658 to shipping station 7660. There, the packaging isoffered for delivery 7662 to the customer.

According to certain embodiments, this delivery may comprise thecustomer receiving the product items in the packaging as conveyed via avehicle (e.g., drone, truck, car, bicycle). According to alternativeembodiments, however, delivery could not feature an automated drop, butrather pickup by a human customer. Such manual delivery options couldutilize visual cues such as indicator lights or screen cartoons.

It is noted that the non-transitory computer readable storage medium ofFIG. 1 further comprises a knowledge base 7634. The data of thatknowledge base may be referenced by the engine in performing machinelearning processes 7690, as has been mentioned previously. Those learnedcharacteristics may be utilized to enhance efficiency of systemoperation and the quality of the customer experience interacting withthe system.

For example, according to some embodiments a customer may be able toprovide feedback about specific items. That feedback can be used tobetter predict preferences and other quality attributes.

Furthermore, information regarding item availability able to be combinedwith expected demand and expected inventory replenishment, could beutilized to incentivize specific consumption trends. This can beaccomplished by, amongst other techniques, placement in web browsers,relative pricing, promotions, and suggestions of recipes that includesuch items or otherwise.

FIGS. 77A-C show front, top, and perspective various views of oneembodiment of a design 7700 for an inspection station. Here, the productitems 7702 enter on the left, move along the conveyor 7703 to thecenter.

The item gets lifted by the rollers, the rollers spin and cameras takepictures from above. FIG. 77D shows a perspective view with the rollers7704 raised.

The items is dropped back onto the conveyors and the items advancesforward with its classification. FIG. 77E shows a perspective with withthe rollers lowered.

FIG. 78A shows a perspective view of an alternative carrier design.According to this embodiment, the carrier 7800 features plastic walls7802 to hold the tray flange in space.

To locate the tray, a click in place feature was added to the carrierand tray. Specifically, when the tray is inserted, it moves past fourclasps 7804 (two on each side of the tray) that are shown in the walledge view of FIG. 78B, and the enlarged view of FIG. 78C. These claspsbend back during installation and then lock the tray in place onceinstalled. This keeps the tray centered in the carrier and it keeps itfrom sliding out or shifting while the carousel rotates.

The carrier embodiment shown may offer benefits by avoiding theconsumption of space otherwise needed to fit the forks into the carrierto remove the tray. Now, without that consumed space, the tabs can besmaller.

Also, because the dispensing tool does not need to fit into the carrier,a higher number of slots can be designed for trays. In this particularembodiment, 2× the number of slots have been added. This affordsflexibility when inserting trays into the carrier, to achieve maximumdensity.

According to some embodiments, an interior of a carousel may be linedwith foam panels. These foam panels attached to the walls with a hookingbracket, illustrated in perspective and side views in FIGS. 79A-B.

Here, the hooking bracket 7900 has teeth 7902 that sink into the foam ofthe panels. The bracket may or may not be glued on, too. Also, thebracket may be covered with some of the same coating that the foam iscovered in. The bracket may or may not be inset into a pocket in thefoam.

The frame of the carousel could have a projecting stud 7904 with whichthe bracket could mate. So, to install the panel, the foam gets liftedso the stud goes through the large holes. Then the panel is lowered downand two or more brackets get secured to the studs as they slide into thekey hole shape.

FIGS. 80A-B show various views of an embodiment of a dispensingapproach. This embodiment 8000 features hooks 8002 that engage the tray8004 from the front of the carrier.

Such an approach may offer certain benefits. For example, it avoidstolerance considerations attributable to the carrier tilting backforward. There will be a tolerance in the location of each carrierrelative to each other.

With this design, the hook fits into a large area and has a bigtolerance itself. Now, the position can be off by >5 mm and still engagecorrectly. This increases tool robustness, and may reduce the cycle timeof the dispensing process because less precision is needed.

FIGS. 81A-C show perspective, side, and top views respectively, of anembodiment of a dispensing approach 8100. Here, the vertical lift designis incorporated into the pop-through conveyors. In place of splines,motor(s) 8102 were put onto each pop through conveyor. This offerspotential savings in cost and complexity, in that stepper motors arecheaper than a single servo plus all the splines and pulleys required todrive them.

This embodiment also features a left-to-right belt drive design 8104that has a fixed timing belt 8106 and pulleys 8108 that move through it.Again, this reduces cost and complexity, disposing the motors onto thepop through conveyor and making the tool easier to manage.

FIG. 82 shows a side view illustrating an embodiment of a dispensingapproach. Here, product items are moved out from the dispensing toolonto a flat table or a set of conveyors that are built into a surface ofthe traveler platform 8200. The traveler than moves to the shipping areaand an order is consolidated.

This approach allows larger-sized items to be stored and dispensed. Suchitems may not normally fit into a bag, but this design saves the manualeffort of walking down an aisle and picking them from a shelf.

FIG. 83 shows a top view illustrating an embodiment of a dispensingapproach. Here, product items are moved out of the dispensing tool. But,instead of the customer bag, the product item drops into a cushionedpocket 8300 that protects the item. The traveler might have multiplebuckets that items can be dropped into. These items are then moved tothe shipping area and consolidated with the larger order.

This could be used when items are too fragile to be dropped onto other,harder items in a bag. A peach, for example, might get damaged fallingonto a box corner or the stem of a butternut squash.
